Is this a permanent error?

[Heart Of Midnight]

This has been the case for a few days now when I log in to the Arena.

After logging in, the following texts will appear on the screen:
Not Found
The requested document was not found on this server.
Web Server at mlparena.com

Going backwards, I still got inside the forum and everything works fine. Refreshing that error message page won't get me anywhere. 
There is no harm in that because I get on the forum, but it is annoying.

This is news to me!
Could you do the usual refreshing your cache etc?

[Heart Of Midnight]

I recently deleted all cookies, saved passwords, and form data. (Thank you my spouse, I personally would not be able to do these as fast as he can!  ) The first attempt reappeared the same error message, but the next time I first logged out of the forum and logged back in it seemed to work normally.
Hopefully that disruption has now disappeared.

A little later: I closed the tab as well as the whole browser. I opened a new one and came here, the same problem always goes on the first moment I log in. Would this also be due to an update to the site...

[Heart Of Midnight]

The same problem still persists when logging in. 
I'm using Edge as a browser, maybe that's the problem and maybe it's not compatible with the update of this site.

I don't use Edge, but when I'm back from my vacation I'll try to poke around.

I highly suggest using a more customizable browser-Firefox is my favorite and very lightweight compared to Edge, but I know how it feels to have a favorite!

that's very strange. Chrome and Edge are pretty much the same browser. I use Chrome and don't have issues. I use apple so i can't test with Edge.

Fireflox here, all fine

I'm on Chrome and recently did a history clear on my browser. I get this same error though I typically just click on my same bookmark to get me back to the right screen

I just had this when logging in on my laptop (after using a different device to access the Arena). I use Firefox. Like H.O.M. said, refreshing the error page did not help, I had to go back and log in again.

The first (unsuccessful) login was through the bar at the top of the page, the second (successful) through the login prompt. Not sure if that has got anything to do with it.

I usually stay logged in all the time so I haven't encountered this problem before.
