I have just ressurected a dormant forum. It was running 1.8.30 on php 7.3 and the server now runs php8.2 by default. I upgraded the forum to 1.8.38 but got quite a few error messages. 

A couple were from plugins that I simply removed as unneeded, but lots of the errors seem to be from core files.

Everything is fine if I switch to php7.4 but php8.0 or newer gets me these errors:

Has the upgrade not gone properly, or is something else wrong? I could run it on php7.4 but I'd prefer not to.

Any suggestions?

please check if there are templates which are not updated

ACP --> Templates --> Find Updated Templates

then update them

Thanks for the suggestion. There were some changes to update, but the outcome was no change at all. 

There were several thrmes and templates not being used, so I deleted them. Still no joy.

The issues seem to be around languages files, and in particular, admin/modules/config/languages.php The file timestamp is the same as all the other new files. Despite this, I tried re-uploading that individual file again. Same file size, same problem.

Later (much later!):

After much messing about I decided that the problem was with missing language definition strings. After a while trying to add them in, I decided that this was an uphill battle and decided to abandon the language files, reverting to the default English (American)

And it worked!

/modules/config/languages.php

you are right! I thought this were old language variables, which no longer are used by mybb

didn't check, my error, sorry

but why did they miss?

I think that the problems are that php8 and higher are more picky about using variables that haven't already been defined. Although it is now mostly working, it's not perfect, so I'm back to php7.4 for now. With 8.2 I get:

Warning [2] Undefined array key "showimages" - Line: 813 - File: inc/functions_post.php PHP 8.2.18 (Linux)
File Line Function
/inc/class_error.php 153 errorHandler->error
/inc/functions_post.php 813 errorHandler->error_callback
/announcements.php 102 build_postbit
Warning [2] Undefined array key "showvideos" - Line: 818 - File: inc/functions_post.php PHP 8.2.18 (Linux)
File Line Function
/inc/class_error.php 153 errorHandler->error
/inc/functions_post.php 818 errorHandler->error_callback
/announcements.php 102 build_postbit
I also had a problem logging in to the admin. It turned out that the problem was that the admin sessions table had a session useragent field that was set to varchar 100. My browser useragent string is 111 characters long.

Changed it to varchar 200 and so far, all is well, using php 7.4

maybe you found a unknown issue on announcements.php

You can deactivate the display of warnings in the acp
ACP --> Server & Optimization Options --> Error Type Medium --> Choose "Errors"

I don't know, why the useragent field was only 100 characters long, on standard mybb it is 200
