Comments.Text: On second glance it looks like maybe you're on ArcusTech and they don't have those installed by default. If you can't get it sorted, hit us up at support@buildwithcraft.com with some CP/FTP creds and we can look into  it and update here with what we find.

Title: Unknown error when trying to upgrade license
ThreadText: # Unknown error when trying to upgrade license
  
  (Asked by: username_0 on 2015-09-21)
  
  I just pushed a site live, and now when I log in to the control panel and get the message to upgrade my license, when I click "upgrade your license", I get a blank modal and a message that "An Unknown Error Occurred".
  
  Everything has been running fine up to this point on the same server, using its ip address, rather than the url.
  
  I'm getting the following errors in my log file:
  
  ```
