WordPress MU

Yesturday I added some plugins to my wordpress mu installations by dropping them in mu plugins.. Today I found out that the visual editor is gone. There is only what is shown if clicking "html" there. You know the buttons and evrything..

I tried adding tinymce plugin to solve it as well. Didnt work and deleted it.

I have unchecked the Profile option and checked it again to see if that solved it. It didnt.. I have cleared the cache.. Didnt do anything.. So I have no idea what is wrong.. Please help me.. :(

I use the latest install.
I am not that good with code. I can change and add after instructions.. But not write up my own.
So please help. :(

Remove the plugins you added. One by one.

I have found the problem. So for anyone else with this problem:

In the first plugin Remove the dashboard.php there was a return befor the <?php

and in the second plugin that caused it.. There was this code:

<script type="text/javascript">
var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl."
: "http://www.");
document.write(unescape("%3Cscript src='" + gaJsHost +
"google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E"));
</script>
<script type="text/javascript">
var pageTracker = _gat._getTracker("UA-5231884-1");
pageTracker._trackPageview();
</script>
