Chris,

The website has returned by himself for magic.

Website broke itself and itself was fixed.

I saw such unexplained phenomena for the first time.

In any case,

I welcome to wordpress

Chris,

The auto wordpress update was fire and at another website with Newspaper but all is ok. All plugins was at the latest version.

Take a look: http://soccerplus.gr/

All works perfect

What can I do?
Why my website was broken?

It is related to the fact that the site is served under https?

Thank You!
Sotiris

Chris,

Here is the error log from NGINX for broken website:

You can see that ../Newspaper/includes/wp_booster/td_page_generator.php calls undefined function is_category() at line 25.

Please help me to resolve the issue.

Chris,

I have clear transients. I don’t have any cache plugin.

The problem still exists!

What else can I do?

Thanks
Sotiris
