Checking to see if this is still an issue. I get the warning from Java that shows real fast, I see this issue was dated back in January.
I am using Windows 10, Edge and:
Pi-hole version is v3.2 (Latest: v3.2)
AdminLTE version is v3.2 (Latest: v3.2)
FTL version is vDev-437af07 (Latest: v2.12)
Is there a fix for this?
Do you still have the problem with Pi-hole v3.2.1?
Yes, using Windows 10, Edge, it will flash the message. Everything seems to work ok.
I must mention it might be linked to DHCP being done by PiHole instead of my router. Yesterday I setup PiHole to handle the DHCP (which was not being done before) and I do not remember getting the Java warning prior to that.
Do you mean JavaScript warning?
Yes, I am getting the JavaScript warning, probably because of using Edge as I have seen that warning from other websites.
That warning is independent of DHCP. If it's flashing up when the site loads then disappearing, it means that your browser is not starting JavaScript fast enough or the page is being generated too slowly.
In some Javascript platforms, if the code is not executing properly then for an optimal suggestion can see Dart vs Javascript that would be beneficial for their programming field.
