Hello, We have a client who is running 3CX V11 [Build 30296] When they open their MyPhone e.g. [http://localhost:5000/MyPhone/] and then login they get this error: We have tried reinstalling the 3cx software on their computers, removing all 3cx references in the registery of the computers and reinstalling. We have even reinstalled windows on a workstation. This also happens if you open the website from the server running the 3CX server. Has anyone seen this? Can anyone advise?
