Hi WanitaPME
Thanks for the update. Apologies for the delayed response. I hope you will find it to be a great resource and place of information.
Generally, this log-in error happens on a MAC, would you happen to be using a MAC when logging in? If you are will need to upgrade to OS 10.12.x.
As a note, you should not upgrade to OS 10.15.x “Catalina” (or above) as this will affect any AccountEdge software you have installed, as well as any 32-bit applications, preventing these applications from working as expected.
If using a Windows-based PC log-in, can you please try logging in from another browser (Google Chrome is recommended) and also try clearing your browser cache.
Please let me know how you go.
