Most of the time everything goes smooth, but sometimes with specific server configuration you can encounter problems. Below you will find some of the most common one and explanation how to solve them.
In shared hosting environments the server resources are shared between several clients. Because of this the time necessary for update can be higher than 30 seconds. If you can set the time that a php script can run on your server, then please set the variable in your php.ini to max_execution_time = 60; If you are unable to set this variable in your php.ini or through an .htaccess file you could try Method 2 in the “CompojoomComment first time install” section.
Because we have unzipped the file folder on your computer we have saved several seconds of execution time for the server’s CPU. If this doesn’t help, you will have to contact your server support and ask them to increase the max_execution_time for php scripts.
