Yeah, it's going around. rooperi posted about it: http://www.chess.com/forum/view/help-support/edit-link-in-posts-not-working
The Edit button in vote chess is broken again.

I am experiencing the same problem as Balachandar. Clicking on "Edit" in Team Comments does not give you access to the comment that you are trying to edit. In the Archive, you don't even get a comment box to write in. It appears that you can edit your post in the general forum, just not Comments in vote chess games.

Most of the team are on a different time zone to me so I need to wait for them to log in so I can see/ask what changed. I've reported the 'submit/edit' issue to them. Unfortunately this isn't something I can fix myself as I'm not a programmer. I'm just the bod who works between you and them. I have to wait on them now.

I am able to edit old posts in group forums, just not Team Comments for the current turn or in the Archive of vote chess games.

For me, trying to edit a group forum post or a public forum post brings up no window to edit the post. ( I tried this on a couple of most recent forum posts. )

Resolved it seems; getting all commemts windows now; or I can't find the vote game it was happening in anymore :)

This has happened a few times in the past. Generally this is the problem:
1. Here is the URL when you click edit:
http://www.chess.com/votechess/game?cid=XYZ&id=ABC#last_comment
2. Here is the URL when the error occurs:
http://www.chess.com/votechess/game?id=ABC?cid=XYZ#last_comment
3. All you have to do is change the second question mark (?) to a ampersand (&) and hit enter and it works.
The "Edit" button in the Team Comments section of all vote chess games is broken. A similar problem appeared a few weeks ago, and then we fixed, but this time, you can't even edit comments for the current turn. The Delete button still works, but you get redirected back to the current turn's Team Comments if you delete something in the Archive.
There were also a few Bad Gateway errors earlier today suggesting that chess.com's servers may be overloaded. There were Bad Gateway errors the last time the Edit button broke too.
