[Plugin: Add Link to Facebook] Access Issue

I changed the post rights to anyone who can post and now I do not have access to the Add Link to Facebook under tools anymore (I am an admin). Please can you advise on how I can get access back to the settings under tools?

The reason I made the change in the first place was because I am using WP Front End and posts from the front end where not adding the link to facebook comments on the posts.

Please can you assist me with these issues? I really love your plugin.

Thank you.
