Strange forbidden access error (JS/TinyMCE)

Hey there,

This is my first post here, so I hope that you guys will be kind enough to give attention to this message. I have been experiencing a weird problem with my WordPress blog ever since I’ve installed it. This does not ever happen with any other hosting company I’m using.

To make a long story short, I seem to be getting strange errors that prevent me from using some great plugins (Link to Post for example) or simple wordpress options like clicking on “Insert embedded media” when I’m writing/editing a post. The error always revolves around js/tinymce …

This is the exact message I’m getting after having clicked: Forbiden access, error type: 403 Requested URL: /blog/wp-includes/js/tinymce/themes/advanced/image.htm?ver=327-1235 is forbidden.

I have taken a screenshot and uploaded it here : https://www.mesfinancesperso.com/WordPress403error.jpg

In this picture, I have clicked on “Insert Image” option from tiny mce and got the error. Hope you guys will be able to help me out on this, I’m out of solutions.

In my cpanel, I went checking the logs and found this:
“client
denied by server configuration:
/home/xxxxxxxx/public_html/blog/wp-includes/js/tinymce/plugins/media/media.htm,
referer:”

I am willing to provide more info if needed, hope to hear from you guys!

Thanks in advance!

PS : All of my folders are 755 and files 644, I’ve triple-checked this.
