Changing hosting caused me to be unable connect to my website
I have a website that uses Joomla 1.5.20 but I have changed the hosting. When I did that I got an error message in the front page saying "Could not connect (0):" I can still login as the administrator and if I try to check the site offline, the login screen can be seen from the home page. I have uploaded the files for the site using Filezilla. I have made the database, the users and managed the database through phpmyadmin. I previously had cPanel but now I have changed to Plesk. How I can I move into my new host without getting an error message? Can Does anybody have a solution to this? Your knowledge with these things can really help me.
