This error is normally due to the misconfiguration of server or incompatible PHP version. The recommended is PHP 5.3.x or 5.4.x .
So here is how to fix it. Im giving three different options, how you can fix this. You can do any ONE OF THEM to get rid of this error message :
- Ask your web host to update the PHP version to 5.3.x or 5.4.x
- Goto Global Configuration > Server > Error Reporting. Just set it to NONE or SIMPLE.
- Edit your php.ini file and set error_reporting to none.
