Disable error_log. Error_log flooding

Question

i got an webserver running and old version of gambio (xt:commerce fork). The error_log in the dir over the public_html is flooding with errors. About 30mb in 15min. How can I disable this log? I can't fix all the errors. Here are a few examples of the errors:

[warn] mod_fcgid: stderr: PHP Notice:  Undefined variable:  key in /usr/www/users/foo//includes/classes/class.inputfilter.php on line 98
[warn] mod_fcgid: stderr: PHP Notice:  Undefined index:   in /usr/www/users/foo/templ
[warn] mod_fcgid: stderr: in /usr/www/users/foo/templates/gambio/source/inc/xtc_show_category_sectionc.inc.php on line 47

They are all errors of: "mod_fcgid: stderr". I tried to grep "error_log" and "error_report" in the public html dir, but i did not find anything.

Here is a part from the phpinfo():

Answer 1

In your php.ini set "display_errors" to 0 and if that doesn't work set the "error_reporting" to 0 or to "E_ERROR" so you at least get the really critial errors logged.

If that doesn't do the trick please comment :)
