Advanced Edit Errors : Cannot post when on Adv settings

I am continung to receive the same errors on my latest WP installation when I select the Advanced Controls (Options > Writing ) while trying to use the Write Post, or Write Page

Here are the errors I am receiving:

WRITE POST
Warning: Unexpected character in input: ” (ASCII=92) state=1 in /home/*****/public_html/blog/wp-admin/edit-form-advanced.php on line 179

My blog is installed on a subdomain; https://www.blog.mydomain.com
and thus all files including .htacces and the index.php file reside in the “blog” folder. This is important as we have our primary CMS system that requires it’s index.php file to be in the root folder.

I’ve triple checked CHMOD permissions for both files and directories but cannot figure out what’s going on.

I’ve previously installed WP in root directories before and have never had this problem. I’ve also spent a great deal of time searching the WordPress forums/ and Codex to no avail.

Any thoughts, suggestions would be greatly appreciated.
Thanks in advanced.
