Thread:Project:Support desk/Content Encoding Error after Migration/reply

Hm, usually this error occurs, when you have corrupted files in your browser cache. So the usual fix is to clear the browser cache. However, I think this won't help you, as you get the error after changes on the server, not in your browser. I can also see that problem and I have never visited this site before, so I surely do not have corrupted files from that site in the cache.

However, this problem can also be caused by other things. One of them is a PHP error, which is given out and so somehow destroys the compression which the server tries to use. This here seems to be such a case. To check that, have a look at the PHP error log to see, if there are any errors reported.
