I am the site admin for our confluence site, and the creator of all spaces. I have been the admin from the start and no other site-admins have ever been added.
For one particular space (I think it may have been the first one created), I cannot access the space permissions.
When I try to follow the instructions for recovering permissions, I go to the admin space permissions page, but the page is covered with a modal titled "Upgrade for space permissions" and I can't access the controls on the page.
I do note that for every Space listed in the greyed out page, the space in question is the only one that does not have a "Manage Permissions" link under the "Operations" heading. This field is blank.
How can I restore myself as a space admin for this space?
