Upgrade From 4.0.3 To Latest (In Subdomain)

Good Evening,

we have a problem that we can not deal with. We have move main site to a subdomain to do as a test upgrade gradually because it is several the number of upgrades

The problem we have is that we can not see any of the pages of the end front

In backend we have normally access

in the frontend we get this message

The page isn't redirecting properly

Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

This problem can sometimes be caused by disabling or refusing to accept cookies.

Now something strange that we observed is that when changing theme we can to get access the site

There some idea what may happen

Thanks in advance


the issue might be caused by multiple reasons - incorrect upgrade of cs-cart settings, htaccess file modification or 3rd party changes in files of theme.

we will be glad to assist you with the resolution so please contact us
