# tail -f /usr/local/apache/logs/error_log

[Tue Jul 14 05:36:19.899752 2015] [:error] [pid 27660:tid 140637045212928] [client 50.28.66.241:50935] Failed loading /usr/local/Zend/lib/Guard-5.5.0/php-5.3.x/ZendGuardLoader.so:  /usr/local/Zend/lib/Guard-5.5.0/php-5.3.x/ZendGuardLoader.so: cannot open shared object file: No such file or directory

How to solved this?

I can see ZendGuardLoader is not installed on your server with the PHP, Please check your php version and try to install it. You can install some php extension on cPanel server with the following command.

/scripts/phpextensionmgr install Zendopt

You can install following modules on your server with the above command.

[root ~ ]# /scripts/phpextensionmgr list
