Problem with Forum module - white screen after F5

Module is installed

As admin i set a new topic and save it.

I can even open the topic from the forums home screen (recent topics).

But when i then press F5 or copy paste the url into another browser window, then i get a white screen. 

Does anyone have an idea why this happens and what i can do about it?

It is probably some php error.  You need to check the php error logs or you can turn on php error reporting to the screen to see the error code.  Once we know the error code, we can then help you.

I wanted to turn on the error reporting, as you said. So i found this in the forums

In inc/header.inc.php

Find :

     ini_set('magic_quotes_sybase', 0);

Just below, add :

     ini_set("display_errors",1);

But it had no effect. The shown website is still only white, and i cant see any error message.

I suggest you turn on error reporting in your php.ini file

I read i should just create a file php.ini and add display_errors = on

Then i upload this php.ini file into the forum folder

But after F5 nothing new happend. 

Could it have something to do with "friendly permalinks" ? I do not have the setting for forums in the advanced settings menu. Is this an error?

I sent you a PM
