there is a problem with the theme installation, like in the screenshot attached. I have made all changes of the php parameters like you request.
“First please check that you are using version php 5.5 >
The solution is to increase the PHP limits.
You can do this on your own .
Find the php.ini file in your Server config files.
For WAMP, its in apache2/bin/apache2.2.22/bin/php.ini
Go to the line “max_execution_time=30” .
Change it to 360 or any other large value.
Contact your web host and ask them to increase those limits to a minimum as follows
