On multiple computers with multiple web browsers and two Surf SOHOs (both running firmware 7.0.2), the display of the Event Log is totally blank. The rest of the web interface is fine.
If have experienced the problem in Firefox, Chrome and Opera. Clearing the browser cache does not fix things. The only browser that seems to work is Edge on Windows 10. I have experienced the problem both with local access to the router and using the web admin via InControl2.
There seems to be another forum user with the same problem.
