When it comes to a SQL server running along side RadioDJ some users have found that their webhosts won’t allow connections to the default SQL port 3306.
If you need a specific port open for this to work it’s probably a wise idea to email your website host support department asking if it’s OK to use a non standard port for use with SQL. Otherwise you may get into trouble with them.
If your webhost doesn’t allow mysql connections on a standard 3306 port then you need to get creative by changing the default SQL port in the SQL server.
It’s not as scary as it sounds. Honestly it shouldn’t take too much to sort it.
1) Backup your RadioDJ database using the database setup tool.
