Hello, first of all thank you for kindly offering your time.
PS was working great until I manually migrated to another server:
1- Transferred files through FTP
2- Imported DB through PHPmyAdmin
3- Modified app/config/parameters file with new DB data. Cleared cache in Advanced Parameters > Performance and deleted var/cache/prod
FrontOffice loads and works, Backoffice too... but some pages are displayed incorrectly both in back and front office.
I attach screenshots of how backoffice's dashboard looks and backoffice's login page looks. Main page caroussel also is not working properly and product pages are not displayed correctly...
Tried disabling and re-enabling friendly-url's in order to get .htaccess recreated, and in both cases I got the following error (I also enabled debug mode):
