we need the full error message, plus the lines of code (5-10 before and after) since we don't know what might have modified your file to have different code lines from ours.

ummm.... next time you're asked for code bits, can you please do text, not screenshots. It's nearly impossible to read/work from screen shots.
Where did you get your copy of 2.1 RC4? (specifically: as a download from this site -- or updated from GitHub?)
Try deleting and re-adding the Q&A, it seems like it got corrupted somehow.

Ok. Do it next time :) But so difficult copy text from error log source code window with line numbers.

GitHub version from Oct 21, 2021 (fixed quotes)
Lines in Subs-Editor.php are same link (https://github.com/SimpleMachines/SMF2.1/blob/806ab1cd2ad06a23fdfe1b5e4742995d7deb4ea8/Sources/Subs-Editor.php#L2263)

Ok. Remove Q&A and disable function. I will observe behavior.
Disаble future, but errors still exist. WTF? ??? What SQL table contains Q&A?
UPD.

8: Trying to access array offset on value of type null
Url for topic contains "?" symbol. Is it right? May be it's hacking attempts?
Do you have 'Search engine friendly urls' enabled?
Under Admin | Features and Options | General?
If so, does the problem go away if it is disabled?
Quote from: shawnb61 on January 27, 2022, 01:34:25 AMDo you have 'Search engine friendly urls' enabled?
Yes, it's enabled. Disable and will observe.
UPD. Don't helps. Errors still added. Page url in error contains "?/" together

that URL indicates that you did NOT disable "SEF urls"
What mods do you have installed?
That code & location match vanilla code. This might be a real bug... Just haven't been able to reproduce it yet...
That error means $row['question'] isn't set for that question. Try this - it won't solve the problem but it will give us more information that can possibly help track down the issue.
Sources/Subs-Editor.php
Find
$row = &$modSettings['question_id_cache']['questions'][$q];
Add after that
if (empty($row['question']))
log_error(print_r($row, true));
That will log the contents of $row if there's no "question".

I don't understand why that url exist in log. But SEF is disabled

But even more surprising the presence of different types of URL in the log

Only happens to guests? Could this be during registration? Or do you allow guests to post?
If you made the code change I suggested there should be additional errors with more information now.
