403 Forbidden Error on a Couple Posts Only

Hi everyone,

I am getting a “403 Forbidden Access to this resource on the server is denied!” error on only a couple posts when trying to either update those posts or even preview the changes.

On all other pages and posts (about 100 others) everything works as it should.

I have tried the usual culprits like a bad .htaccess file, disabling ModSecurity, disabling plugins , caching and tried everything I could think of and found doing some searches on other sites with no fix found.

I have checked with my host and there is nothing on their side causing the error.

It is strange because the rest of the pages and everything in the admin side works properly. The error is only on a couple posts.

If anyone has any ideas what to check next it would be greatly appreciated.

Thanks in advance for any helpful input.
