I looked into the issue and it seems like this is a hosting problem most likely to do with mod_security. Please contact your webhost for this. I’m trying to see if i can revamp the settings page so it does not trigger this error.

Dear Sir/Madam,
Recently, I’ve been experiencing a problem whilst using a WordPress installation. It has come to my understanding that it is most likely a mod_security issue. Upon saving the setting page for this plugin i get the following error:
Not Acceptable
An appropriate representation of the requested resource /wp-admin/options-general.php could not be found on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
Please see the attached screenshot for the request on which it occurs.

I had the same problem. I just went to an earlier version 2.6 and it works alright. Hope this helps
Thank for the feedback regarding this issue. This week I’m busy with college exams, but I’ll develop, test (very important) and commit the update somewhere next week.
