Hi,

i have a problem with inserting some data from tinymce to database.

When i write something in tinymce and don`t give to many styles it works fine and everything is ok, but when i copy some text from old site and paste it to tinymce and try to store it to database it disappear, same thing is happen when i copy some text from word.

XSS filtering off, using active records.
