I took a look at your account and it looks like you have made changes to your php.ini file, but it only affects the immediate files in your public_html directory as you have not set it to be recursive. Setting your php.ini to recursive should fix the max execution time errors.
I am not sure where I should put the line of code, so I put it at the end. Will this work???
# To set your custom php.ini, add the following line to this file:
# suphp_configpath /home/yourusername/path/to/php.ini
