1. You are now on 'fris' , not 'absolut' , so any urls you used that contain 'absolut' should be replaced with ones with 'fris'
2. They are finishing up with the "cleanup" scripts. Which means that cPanel is sometimes unreachable. Currently I show
https://fris.x10hosting.com:2083/login/ sometimes working, sometimes giving a 500 error.
3. Database issue: When you are able to get into cPanel, go to the Database section, click on Remote MySQL and add int.fris.x10hosting.com to the list. If it is already there, or adding it does not help, post back here.
