We have an installation of SharePoint 2010 in which access to SharePoint designer has been granted within Central Administration, as well as at the site collection level.
Whenever I try to open the site, or any of its sub-sites in SPD, I get an error stating:
"You do not have permission to do this operation. Ask your web site administrator to change your permissions and then try again, or log in with a user account that has this permission. To log on with a different user account click OK."
My user has full control over the site collection and the site itself. I've also tried using the farm admin account, as well as trying on several machines.
I'm currently at a loss. Anyone have any ideas?
Not sure if it matters or not, but this site is setup to be accessed via https only -- don't think that would matter at all, but worth mentioning. I have a redirect for any http traffic. I did revert that to verify I still could not access the site in SPD. Also, I just checked to make sure the site was not set to read-only, and it was not.
Removed and set as an answer below, will mark as the correct answer when it lets me.
