I am in the same boat, I ran the auto-update and the UI in chrome will not work correctly. I am to the KB to see what might be going on?

Are you guys using Grammarly by any chance? Please try to disable it, we currently have an issue with that specific plugin.

Yes Your right. Grammarly is the thing.

Just turn off for PRTG window...

@prozan Disabling it in Grammarly didn't do the trick for me, it actually made it worse :D Did it work for you?

I'm also experiencing this problem. Removing Grammarly indeed made the difference.

Is this getting patched? Quite annoying.

This is likely caused by the plugin interfering with PRTGs javascript somehow. We're in contact with Grammarly regarding this already.

In the meantime, you could open up a support request with them as well so this gains some traction :)

I too am having this problem (or something similar), but do not have the Grammarly extension. PRTG does seem to work incognito, so it seems likely that some extension could be conflicting. This is what I have active: 1Password Cisco WebEx Google Docs Offline Google Hangounts IT Glue Password App (Passportal) Switchvox Dial Switchvox Screen Sharing

We did not have this problem on 18.4.46.

Some from quick testing it looks like it may be the IT Glue Chrome Extension that is causing the issue. I'll leave it off and confirm.

Ok, so disabling Grammarly fixed most of the issues, However, now when I go into any settings it will try to rename a few fields with old data from another edit. Putting chrome into incognito fixies it. I am sure it is another extension, it is odd these issues only started after the update to (18.4.47.1962). I have always had an issue with the scroll bar not rendering, but a refresh fixes it.

Are we talking about credential fields here? Or do other fields get populated as well?

Same problem in Chrome. In my case it was the "Acano" extension.

Any options to add PRTG to an exclude list for the extension?
