Apache2 error in log files

[Hans]

In my /var/log/apache2/error.log files there are a loto of errors, like:

[error] an unknown filter was not added: PHP

Is this something to worry about and what can be the reason that these lines occur?

:confused:

Does everything works oke?

if so then nothing worry about, but send the error report here

if it does not work then you must for sure send the error report + httpd.conf (apache conf)

Yes everything is functioning, just wondering why...

Thanks for your invitation, but i do not use msn.
Chatting is a waste of time to me.

Can anyone else give me a second opinion about the error lines within my apache2 log files?

I've read a thread here: http://www.howtoforge.com/forums/showthread.php?t=4770&highlight=%24go_info%5B%22server%22%5D%5B%22apache 2_php%22%5D and followed up Till's instruction, now the messages don't appear anymore.

(but i'm still wondering why the messages could appear).
