error message?

[Aeonium2003]

Here's what it says on the top left hand corner when I look at any of the different forums. It doesn't let me attach screenshots, so here's what it says:

"[phpBB Debug] PHP Warning: in file [ROOT]/viewforum.php on line 628: Undefined array key "b"
[phpBB Debug] PHP Warning: in file [ROOT]/viewforum.php on line 634: Undefined array key "b""

If your screenshot is a .png file, try converting/resaving it to a .jpg file before uploading it. I believe .png file uploads were disabled sometime ago.

Try PNG again, it may work out now. In any case, JPGs are a better choice.

I got another crazy message at the same spot while looking at a member's profile. Seems like PNGs work now.

I've been getting the same one as in post 2 above, just browsing the site. It appears if I click on a subforum (e.g. Agavaceae Talk), no matter which one.

I have never seen it. I will clear the forum cache, and suggest you clear your browser cache. Also, try a different browser. Let me know if that helps.

Also, my server upgraded its PHP version about two weeks ago, and it's possible that is responsible. Does that timing roughly coincide with the issue? I just set the PHP version back from 8.0 to 7.3.

no more messages now, didn't clear cache or change browser.

It was the PHP version then, combined with some factor of your computer setup that is different from mine. Who knows? All good for now, and that is what matters most.
