Forum disapears

Maybe I should post this somewhere else, if so I apologize in advance.

When I activate the latexrender module or the bbcode_video module, the forum just disapears. I get a blank page. When I turn the module off form the admin interface, everything works again.

What did I miss ? (I did set permissions on the directories that latex needs)

TIA

What version of Phorum?
What version of php is being used?
New install?

Any modifications to the phorum code, or integration with other pages on your website?

Sorry, I forgot to give details :)

Phorum has issues with php7.x+ as you have experienced.
The particular issues vary a little bit by operating system, host server, etc.
The mods you are using have not been updated for longer than the main phorum software.

For instance: (version 1.0.10) video mod has http: , instead of https: , hard coded in it. It will not work without modification for any of the commercial (youtube, etc.) sites.

Go to this link [www.phorum.org] and download the latest dated (2016) BBcode video.php

Then read the messages on page 9 of this topic.

As for the Latex mod, read the messages with that topic to start. [www.phorum.org]

Thanks a lot. It helped.

Yet I still can't see my videos, but I posted here in the Video Post
