Well, thank you for writing such a good update script!

I made a duplicate site since it was going to be so hard to rebuild the site with a new theme. Then having built the copy of the site and imported the old database, I thought, why not give the updtae script a go.

The bad thing was that when I imported the database to the duplicate siteI did not change the site url. Dumb mistake. So when I told the update script to make its changes I was in fact on the live site not the duplicate.

The good news was that the script worked. Well done.
I had to open each page and change the template, I had to put widgets back in a few sidebars. In 10 minutes I had the site working again.

Thanks so much.

So for anyone else:
The update script works for update from version 3.8 to 6.
My site only had about 10 pages
Posts on my site all looked much the same.
I had some custom css for integrating plugins to the theme.
In other words my site was not doing anything dramatic or different.
Pages need their template choices checked/redone.
Widgets in sidebars need to be reset, 3rd party plugins will be missing.
Custom css needs to be copied over as well I guess.

Cheers

Looks like you can use the existing setup to choose a category AND a tag.
If my category is “May issue” and my tag is “people” then only those items that exist in the May issue category with a tag of people will show.
Effectively an AND filter.

I am voting with OuweAap, I want to show posts that are in both categories, for example the “May Issue” of the newspaper (which is a category), and the “life” category.

It took me an hour to work out that the filter is an OR not an AND combinator.

Suggest you add this to your documentation, maybe here:
https://forum.tagdiv.com/modules-and-blocks/

START
Category filters
To show items from more than one category add them here. (This is an OR filter).
No AND filter is available to show items that appear in more than one category.
