Apache2/PHP error after phpBB3 install

I followed the Perfect server setup for Hardy Heron, ISPConfig, and added phpAdmin and Squirrelmail.
Everything seems to be working fine now. Web sites seem to work, some email works (to gmail, etc.).
However, after I installed phpBB3 on an individual site (I install one phpBB3 per site), I get the following error in the Apache2 logs:

[Mon May 05 21:40:17 2008] [error] an unknown filter was not added: PHP
[Mon May 05 21:40:17 2008] [error] an unknown filter was not added: PHP
[Mon May 05 21:40:23 2008] [error] an unknown filter was not added: PHP
[Mon May 05 21:40:23 2008] [error] an unknown filter was not added: PHP
...
and so on. Seems to log these only if someone is into the phpBB3 link.

Anyone have ideas on why? I've searched a bit, but find comments that are a couple of years old. I would think the current howto would cover this issue now. Is it Apache, or does phpBB3 do something without regard to the ISPConfig configuration?

Thanks

 

Resolved - PHP error

Ok, I did some google searches and came up with Till's solution:

http://www.howtoforge.com/forums/showthread.php?t=4770

where:
Change the line:

$go_info["server"]["apache2_php"] = 'both';

to:

$go_info["server"]["apache2_php"] = 'addtype';

in the file /home/admispconfig/ispconfig/lib/config.inc.php

I made the change, edited one site, and tried 2 sites with phpBB3, and see no further errors. (so far)...

Thanks to this forum...good job
