I needed to move an installation of PRTG from Windows 10 to Server 2012 R2 (For the obvious reasons mainly control of updates).
I had to update my PRTG installation (both running 22.214.171.12457), data copy and registry went ok and the server started. Once I logged in and went to Devices then selected a device, then selected a sensor and then clicked back the UI below the 'Overview - 2 Days - etc...' tabs was blank. selecting any tab resulted in a prtg popup message with 'error not found'. After doing a developer tools check there was a call to 'document.location.refresh()' that was failing on line 307 of _Prtg.TCT.Plugin.js.
After changing this line to 'document.location.reload()' I don't seem to have the problem... Is this a bug or is there something else going on?
