GET variable name length limit exceeded

When making changes to your website using the CMS admin panel, you can encounter the issues indicated below in either your custom error log file OR the Apache error log file.

[STDERR] ALERT – configured GET variable name length limit exceeded – dropped variable (attacker ‘xx.xx.xx.xx’, file ‘/home/user/public_html/index.php’)

This is a result of suhosin being compiled on the server using PHP. It is not necessary to disable suhosin on the server in order to get around this. The problem will be resolved by raising the suhosin.get.max_value_length limit. Suhosin.get.max_value_length has a 1024 restriction by default. Doubling the value is safe.

If you are hosted on a shared hosting plan, ask your webhost to increase the limit for your account. If you lease a VPS OR Dedicated Server you can increase the limit in server’s php.ini & restart apache.
