I was trying to install themes in wordpress and this error occured - Fatal error: Maximum execution time of 30 seconds exceeded in C:\wamp\www\wordpress-3.5.2\wordpress\wp-includes\class-http.php on line 953. What is this? I an not able to get it.
Find your php.ini file, and edit the line..
max_execution_time = 30
Raise it to 60 or whatever you need. Not sure of the location of your php.ini on WAMP, but remember you can create a phpinfo file to view your php configuration to find the source of php.ini.
