Guess what?

Upgrading to from PHP 8.2 to PHP 8.4 seems to have solved the problem.

So it goes! Thank you!

OK.

I hadn’t looked back at this since your last couple messages: the error message about “POST Content-Length” is definitely the cause of the problem you were seeing. Your host said they had set the limit to 512M (512 megabytes) but the error message indicates the PHP post_max_size was instead just 512 (512 bytes). That’s really really small (512 bytes is a million times smaller than 512 megabytes) and you’ll go over it very easily when submitting practically any form, like you experienced.

There’s nothing about PHP 8.4 vs. 8.2 that’s different here, but upgrading the PHP version probably got you on different php.ini settings which avoided this issue.

Thank you! Great to know the underlying reason for the problem, but I’m mostly just glad it’s working.

Now I can pester you all with my 15 other problems!
