Hi there,

I've found I'm unable to add attachments to posts with PHP 8 or higher on Altervista, even though this issue doesn't occur on my personal website which uses a paid host.

If I use PHP 7.3, I get a green tick next to attachments after uploading them, but on PHP 8 or higher I get an exclamation icon and the attachments don't appear in the post after I click submit.

I can't see anything in phpBB's error log in the ACP, so perhaps someone could look in the logs for an error at roughly 2:57 PM on Fri Mar 20, 2026?

I did report this some time ago but never got a resolution, however it's more important now that PHP 7.3 is being removed soon.

Best,
Hamish
