I have Joomla 2.5 installed on Windows 7 with Apache 2 and PHP 5. I have countless PHP errors in the log like the following:

[01-Sep-2012 19:33:55 UTC] PHP Strict standards:  Only variables should be assigned by reference in C:\ammon_dev\ammon\plugins\system\jquery\jquery.php on line 24

I tried disabling error logging in php.ini:

error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT

Unfortunately that does not make a difference.

Joomla isn’t in debug mode, and I am sure that I’m editing the correct copy of php.ini because other changes I make to it take effect.

Any ideas why I am getting so many errors or how to stop it from exploding the log?
