Hi there,

There was an issue with the version you have installed:
https://www.paessler.com/prtg/history/stable

Therefore please download the fixed version from the following URL and install it manually on top:
https://downloads.paessler.com/prtg/prtg.zip

Does PRTG start normally afterwards?

Best regards.

Hi there,

What version where you using before and what version have tried updating to? After checking the issue above it seems that you have done a massive downgrade from 18.x.42 to 17.x.x.

Best regards.
