On Cs-cart says I have an update available. When I check PHP script timeout it just hangs.
Do you see any new records in the server error logs?
Only way I could update is to use the command line; Just curious why? Nothing in error logs
Try to contact CS-Cart support team with this issue. It should be examined on your server directly
If you have DEBUG active, it will chew up a ton of memory. Turn it off before upgrade and turn on DEVELOPMENT.
