Clicking topic in forum generates 500 error but topic exists in database

[truecrimson]

I have a topic with multiple replies that appears on the forum but when clicked generates this;

This page isn't working www.thecrimsonpirate.com is currently unable to handle this request.
HTTP ERROR 500

I used PHPMyAdmin to check the database and the topic still exists with all replies.

I am running SMF 2.0.15.

Here is the other information I have been able to obtain;

My forum is restricted to only members and has restricted boards that are not visible to all members.  If you need access in order to help me PM me and I will set it up.  If you can talk me through fixing this I will do my best to follow your directions, though I am not an IT person and my knowledge is very limited.

Thank you.

SMF 2.0.15 does not support 7.2 - that may be part of the problem.  You need to downgrade to 7.1.

SMF does not officially support MariaDB at this time - that may be part of the problem.  Note we have plenty of folks on MariaDB with no issues.  But we have encountered MariaDB implementations that have reserved words that conflict with SMF. 

Was this forum working fine previously, or is it new?

What mods do you have installed?
