Ok, I double checked the database credentials and made sure the prefix was included, as directed by the hosting provider, but still getting same message.
I also receive these errors on the page:
Warning: mysql_fetch_assoc() expects parameter 1 to be resource, boolean given in /home4/whsbd/public_html/Test/WA_Globals/WA_Globals.php on line 41
Warning: mysql_free_result() expects parameter 1 to be resource, boolean given in /home4/whsbd/public_html/Test/WA_Globals/WA_Globals.php on line 67
If I delete these I can access the PowerCMS login page but when I log in I get the no database selected message.
