Cannot edit posts (solved)

A little while ago, in a thread I'm involved in, I needed to modify my post to change a link to point to a more recent version of my program. When I finished quick editing my post, it gave me the green loading bar at the top of the screen (the one it gives before it finishes). It was still there after a few minutes, so I went off to get something to eat. When I came 20 minutes later, it was still there, and no apparent progress had been made. So I canceled the change, and then used the "Modify" button to do a full edit. But after I finished and tried to save the edits, the computer sat there for about 10 minutes with the status bar (at the bottom) showing a loading bar. Then out of nowhere, it switched to a blank screen with this text:

Database Error: MySQL server has gone away.
File: /home/nitwose/public_html/nifflas/forum/Sources/Subs.php
Line: 2496

I tried again, but the same thing happened. Does anybody know what happened and maybe how to fix it?

MySQL server has gone away.

 

Errors occur sometimes to MySQL, it's normal, especially when the database is so huge.

This is bad luck

Well, (expletive). Do you know if there's anything I can do?

Try again in the minute or two, this should help

You've just visited at a busy moment for the server. There's nothing you can do, there's nothing we can do either. The only thing you'll have to do is try again at a later moment. If things persist you could try clearing your temporary internet files and close your browser afterwards.

Looks like you were right, I just needed to wait a while before it started working again. Thanks!
