Hi SodSy,
Thank you for your post.
Joomla 1.5.15 introduced a new security rule in the .htaccess however, this rule was commented out by default and had to be manually applied because it would have affected many Joomla extensions.
If this rule was applied the most common error would be:
: "
www.mysite.com/plugins/editors/fckeditor...s_template.xml" (HTTP Status: 403).
This is because the OLD JoomlaFCK editor doesn’t work with a new security rule if applied; this is due to the way in which the editor works. However, there is a workaround which is to commented out the rule in the .htaccess file or alternatively upgrade the NEW 3x version which is compactable with all recent changes in Joomla.
Kind regards,
Paul
