Hi I'm Having the same problem even with the corrected code on a new install of 1.3.9h

<FilesMatch ".*\.(js|css|jpg|gif|png|html|htm|xml)$">

if I add |php| to the list then it works am I leaving the folder open by doing this? I tried change the permissions to 755 and 777 with no luck.

The code i have is:

<FilesMatch ".*\.(js|css|jpg|gif|png|html|htm|php|xml)$">

Error message without the |php| is:

Forbidden

You don't have permission to access /shop/editors/tiny_mce/plugins/Im ageManager/manager.php

Thanks for your help
