One more piece of info – connection to database works alright when it comes to forums, topics, posts (they’re all listed on homepage). But when it comes to users (which is a link to WP), it fails and gives the above error.

Also, if I want to click through on a particular forum/topic from homepage, it gives 500 Internal Server Error

Any idea what this could be about? Where the reason is?
