Hello Support

We have updatet CloudPanel from 3.0.x to 3.1.1536 over the Migrationversion 3.1.0030.
After the Update we have two Erros. One Error we fixed with P20160513_159.
Another Error is, when we click off Companies in the left Pane, then list all Companies in the middle Pane.
When we then click off a Company, whith activated Exchange we get a Runtime Error.
When Exchange for the Company is not activeted works fine.
