Dear Forum Members,
Recently, I have upgraded my CS cart Multi vendor version from 4.12.2.SP2 to the latest CS cart Multivendor version. After upgrading, I have encountered some issues on the frontend store. Thus, I have restored my site and database to the old CS cart Multi vendor version 4.12.2.SP2 using the "server rewind" feature on the control panel from the hosting provider.
Now the problem is that I can login to the backend admin panel using my admin account. But the admin panel page nothing response after login. Please refer to the attached screenshot.
Could you kindly advise where was the mistake?
Thank you and best regards,
