Hi,
Thank you for investigating.
I did some research too and pretty sure the problem is in the way it is managed by the theme. We have no issue with any other Ajax requests (including other WP projects using CF + Rest + GraphQL).
In the meantime I found a work around.
There is a setting in CloudFlare in the Cache section to set a rule to bypass cache in presence of a cookie. This way the authors can navigate in the site without the “loader” jamming 🙂
I still hope the devs find the fix, would be nice for others too.
But what would be even nicer is that those requests could use GET … opening the magics of cache <3
Saturday http://www.welovetennis.fr hit over 1 million visits… not easy to handle such load without cache.
Fingers crossed 🙂
Thanks for reading and wish you all a nice day.
reminder: in previous messages, logs confirmed that the POST request did get to the backend and that it was the backend responding 403, not cf.
When using a cache plugin in WordPress (aka W3-TotalCache or other), it will disable the cache for authenticated users and build the page for all known users.
But when using ClouFlare, when page is in cache, admin users get same page as everybody.
So navigating on the frontend of the site admins have time to time the wordpress admin-bar (cf cache miss) and no admin-bar (cf cache HIT)
So when admins do have the admin bar the infinite scroll works as expected, but on pages without the admin-bar (cf cache HIT) the Ajax request reaches the server and bounces status 403.
Bellow you’ll find the request in curl
If I run that request without the line “-H ‘cookie’ … ” it works just fine.
So I believe the payload / ‘–data-raw’ section holds something about the authenticated user that has to match the cookie, and that when it finds the cookie and not the relevant data in the payload, the request gets rejected.
(I’ve tested all I could. Things like disabling any security plugins like Wordfence etc..)

and here i took things one step further but the result is almost copy paste for devs
Just you wouldn’t have to put debounce_ajax_call in ‘window’ context, I was forced to it because my context is .on(‘foncsin’) (out of tdAjaxSearch object)
so in this hack i just debounce the actual ajax request (and not the do_ajax_call) that is changed to ‘GET’ (and removing the setTimeout)
line 19 there is
tdAjaxSearch.process_ajax_response_mob(b)
if you change it to
tdAjaxSearch.process_ajax_response_mob(b, a) // a being here the search term
then in function process_ajax_response_mob() you have the term without having to read the response 🙂
I was just playing around to look for ways of making life easier in there.
hope it can help
The webiste I did with your theme has gone from small trafic to become nº1 in tennis in europe… thanks to your work !!
But that means that for Roland Garros I could have to handle over 500k daily visitors (we are yet over 70k)
It’s not that big… I have other site running 2M (not wp tho)
As the site uses infinit scroll… caching even of 3s would help
I coud suggest a very simple change that could change the deal about caching (the site is behind varnish)
php side have all ajax $_POST changed to $_REQUEST
then I could fiddle to change all ajax POST to { method:’GET’, cache:false }
it adds a &_=134567 that can be removed from url in varnish and then hit a common cache
… no rush, just clues 🙂
Hi Calin,
I was very busy with migrating that 140k pages site, so I didn’t take the time to look into this until now.
So I just prettified the script_for_front.js and had a quick look and the fix seams real easy.
somewhere around line 350 I see this
a.jqueryObj.find(".tdb-head-search-form-input").keydown(function (b)
{
if (b.which && 39 === b.which || b.keyCode && 39 === b.keyCode || b.which && 37 === b.which || b.keyCode && 37 === b.keyCode) tdbSearch.set_input_focus(a);
else
{
if (b.which && 13 === b.which || b.keyCode && 13 === b.keyCode) return b =
a.jqueryObj.find(".tdb-aj-cur-element"), 0 < b.length ? window.location = b.find(".entry-title a").attr("href") : jQuery(this).parent().parent().submit(), !1;
if (b.which && 40 === b.which || b.keyCode && 40 === b.keyCode) return tdbSearch.move_prompt_down(a), !1;
if (b.which && 38 === b.which || b.keyCode && 38 === b.keyCode) return tdbSearch.move_prompt_up(a), !1;
(b.which && 8 === b.which || b.keyCode && 8 === b.keyCode) && 1 === jQuery(this).val().length && a.jqueryObj.find(".tdb-aj-search").empty();
tdbSearch.set_input_focus(a);
setTimeout(function ()
{
tdbSearch.do_ajax_call(a)
},
100);
return !0
}
});
looking just on the last few lines
replacing this
setTimeout(function ()
{
tdbSearch.do_ajax_call(a)
},
100);
by that
debounce(
setTimeout(function () {
tdbSearch.do_ajax_call(a)
}, 0),
250
);
first you would need this https://davidwalsh.name/javascript-debounce-function
actually coming from an old version of underscore (it works!)
function debounce(func, wait, immediate) {
var timeout;
return function() {
var context = this, args = arguments;
var later = function() {
timeout = null;
if (!immediate) func.apply(context, args);
};
var callNow = immediate && !timeout;
clearTimeout(timeout);
timeout = setTimeout(later, wait);
if (callNow) func.apply(context, args);
};
};
this is the actual up to date function on https://github.com/jashkenas/underscore/blob/master/underscore.js
but perhaps underscore can be useful to have in such a project
I see here that _.debounce requires _.delay who needs restArguments
this could be the “light” way that does the trick too
_ = _ || {};
_.debounce = function(func, wait, immediate) {
var timeout, result;
var later = function(context, args) {
timeout = null;
if (args) result = func.apply(context, args);
};
var debounced = restArguments(function(args) {
if (timeout) clearTimeout(timeout);
if (immediate) {
var callNow = !timeout;
timeout = setTimeout(later, wait);
if (callNow) result = func.apply(this, args);
} else {
timeout = _.delay(later, wait, this, args);
}
return result;
});
debounced.cancel = function() {
clearTimeout(timeout);
timeout = null;
};
return debounced;
};
_.delay = restArguments(function(func, wait, args) {
return setTimeout(function() {
return func.apply(null, args);
}, wait);
});
// Some functions take a variable number of arguments, or a few expected
// arguments at the beginning and then a variable number of values to operate
// on. This helper accumulates all remaining arguments past the function’s
// argument length (or an explicit startIndex), into an array that becomes
// the last argument. Similar to ES6’s "rest parameter".
var restArguments = function(func, startIndex) {
startIndex = startIndex == null ? func.length - 1 : +startIndex;
return function() {
var length = Math.max(arguments.length - startIndex, 0),
rest = Array(length),
index = 0;
for (; index < length; index++) {
rest[index] = arguments[index + startIndex];
}
switch (startIndex) {
case 0: return func.call(this, rest);
case 1: return func.call(this, arguments[0], rest);
case 2: return func.call(this, arguments[0], arguments[1], rest);
}
var args = Array(startIndex + 1);
for (index = 0; index < startIndex; index++) {
args[index] = arguments[index];
}
args[startIndex] = rest;
return func.apply(this, args);
};
};
Perhaps you all ready have underscore? but didn’t spot it in that js
… it’s got nice goodies and comes handy 🙂 (17.6 KB not so bad ?)
hope this comes helpful, have a nice day.
oups editing code here is dangerous ö
Hi,
Yes I use a template from Cloud and I believe I’ve got something wrong on my header as it adds almost 1M of html when I compare http://www.welovetennis.fr and www2.welovetennis.fr for adding just 2 logos… I must have something in there. I’ll just recreate a header from scratch (I had based myself on Template 3 header of Cloud lib, I’ll try starting from blank template this time)
I didn’t see them in search console… yet…
But I could see yahoo, bing and google crawling them. And that yes is not good.
On a 150k pages website this is not helping us (and having wget doing the same is really not a good sign)
This is how I wasted a few hours.
I added this function in prod then put a tail -f on logs to check all was good
Then I spotted those broken url and thought my function was somehow responsable.
Then been hunting for couple hours checking all links. seeing wget -r was doing the same as the crawlers convinced me of investigating further.
// adapting ponctuation for french language
function filter_the_title_fix_ponctuation( $the_title, 5 ) {
// $the_title = html_entity_decode($the_title);
// $nbsp = html_entity_decode(" ");
$thinsp = html_entity_decode(" ");
$the_title = preg_replace('/ +([\?\!\:])/', $thinsp.'$1', $the_title);
return $the_title;
}
Thanks for your help
PS
by the was, perhaps you guy could really benefit from using a private stackexchange … this forum isn’t very helpful when trying to find already answer questions…
Hi,
No. We just want featured video function to fetch a thumb for the links to the post.
We found a trick, is to first save the post with format video as draft and having the “featured video” field set.
This fetches the featured image, then we clear the “featured video” field before publish. This way it comes out the best for us: a thumb on link to the post and no featured image on the post single page.
Is it possible that the function to fetch featured video thumb would work with tweeter videos ?
That would be nice for us.
Have a nice day
perhaps having a quick look here you could advise me better
I don’t seem to find how to set header background transparent ( the megabanner is part of the header based on Header Template 3 )
Thanks again 🙂
