I changed from server to a more modern one (from hivelocity to a2hosting), I made a backup of all the crm information and copied it to the new server and I gave the necessary permissions as it appears in this link or the basics permissions to fix the interface and css.
But the problem was that it generates this error "Uncaught ReferenceError: $ is not defined". I have been doing this many times and installed many sugarcrm and this is the first time I have this error.
To make sure and rule out another problem, I did the same copy of information and processes to a godaddy server and it worked perfectly.
Could you help me?
Thank you very much
