The site after the transfer on the main domain does not work correctly, but on the subdomain everything is in order. Why?

Question

Joomla

Friends, is there an explanation for the following fact:
After the transfer, the site does not work correctly on the main domain, but everything is fine on the subdomain. Why?

The hoster unsubscribed saying that contact the CMS developers

Main domain

Subdomain

The incorrectly working site does not have a top tag, the drop-down menu does not work in the header at the very top, the product carousel does not load below, tabs do not switch, the review slider below does not work.

I will be grateful for help.

Answer 1

The top runner is also missing in the code on the main domain. Look in the CMS settings, is it enabled on the main domain?

Answer 2

Both sites were transferred by restoring from akeeb backup. The archive is the same there and there. With all this, guys, thanks for the help, I'll look.

Answer 3

See logs. If there is an error during the transfer, you will find it.
