I am using Pro Sites 3.0.2 plugin (updated this morning) and am having the following issue.
I am using both Pay to Blog Module and Posts/Pages Quotas and 2 levels.
I have level 2 set as the unlimited level to remove quotas. Every one else is limited to 6 posts and 6 pages (screen shots included).
Whenever I try to publish a page, The publish button says "Submit for Review" even though there are only 4 pages published and the blog has not met the page quota. The user account is an Administrator on the blog. If I log in as a network admin, I can create pages. If I disable the Posts/Page quotas module, I can create pages.
Seems to be a bug unless I am misunderstanding how the quotas work.
