Many reasons are in this case but in our investigation with some sites, we'd like to share some solutions to rectify it. 1. Time out of your server, its default value is 30 seconds and if your site uses many apps, you should redefine its attribute value to 120 seconds. Note: its variable is "max_execution" in PHP.ini file 2. Memory limit, you often set it as 32MB or 64MB to meet for installing phpFox platform but you do not understand that the site also contains majority of apps and each app needs a bit memory to compile. Our advice is 128MB - 256MB as the best. Note: its variable is "memory_limit" in PHP.ini file
