Thanks, but actually I think you have the wrong zip-file here; it's the one for hiding text from guests.

Sorry, now I've uploaded the correct one. :p

Thanks a lot. It seems to work now. I'll check in tomorrow.

Some more information: It worked to a certain point, but then there were many threads that it didn't manage to tag. When I changed in AdminCP -> Tagging Options and set it to run as Super Moderator it worked, since many of the threads in question were in hidden sub-forums. From some point earlier today all that is logged is "Tags are not added", which is good.

However, some new public threads have been created today, and these have not been tagged, even though it's been a few hours and the autotagger still runs. Is there a setting somewhere that stops it from tagging new threads?

That the problem was fixed with a small change.

Upload files back to FTP, nothing else is needed.

Maybe I did something wrong, because I uploaded the files and also did the add/import XML again. Now it tries to tag a lot of old threads over and over again, but without success. I have set tagging to be done using Super Moderator privileges, but to no avail.

I just found that I get a lot of database errors, one every few minutes. One example below (slightly redacted with xxx):

Invalid SQL:
SELECT * FROM node WHERE nodeid = ORDER BY created DESC LIMIT 0,1;

Judging by the mysql error, the files belong to the old version.

https://vborg.vbsupport.ru/showthread.php?t=328436

Will it work for 3.8 version?

And what happens to already old tags ?

Too bad, it works on 5.7.4 and PHP 8.26 but I turned it off.
It automatically created tags from all moderator topics, for example with message reports, so that in similar topics there is "xxx reported a message" ...
Can this be resolved?
