What terms did you try when SEARCHING for a solution: rich text 500 error

Write your message below:
My server was on Ubuntu 18, and with the new Apache CVE, I needed to update. I set up a new server with Ubuntu 24 TLS, and installed Hesk 3.45. I then exported the database from the old server, and imported it into the new one. That accomplished most of the work, and I then manually duplicated settings from the old system (not copying the settings file).

We have the Rich Text editor enabled, and after ticket came in, I went to reply. When I submitted my reply, I got a 500 error. I rechecked permissions, and wasn't able to find an issue. I actually have 3 installations of Hesk installed on this system, once for each dept, and they all exhibit the same issue with the rich text editor enabled. If I set it to plain text, no issues. I'm guessing it must be a PHP or Apache issue, but I'm not seeing problems with any other part of Hesk. Even in the knowledgebase, I can use rich text just fine. It's only with ticket replies.

PHP 8.3.6
MySQL 8.0.36

Thanks,

Without any other error messages my guess is you don't have the DOM extension enabled in PHP (should be by default):
https://www.google.com/search?q=php+enable+dom

You can confirm this by looking at your phpinfo; is there a "dom" section with "DOM/XML" set to enabled?

Thank you, that fixed it

This was a new installation, and I just installed php using 'apt install php'. Perhaps they've taken the php-xml out of the standard install. Installing php-xml, then adding dom to the extensions section did the job.
