Hello, I’ll try to put these patch but it doesn’t solve the problem
As it was proposed by Raheel Hasan
I find and replace the regex in class.egw_framework.inc.php
'."\n";
with
'."\n";
and find and replace the regex in fckeditor.js
navigator.appVersion.match(/MSIE (…)/)[1] ;
with
navigator.appVersion.match(/MSIE ([\d.]+)/)[1] ;
It seems to be ok
