I think the Post/Page Quotas module is not behaving the way it should or maybe am wrong.
Here we go, i setup a test site, with a two days free trial. THen i upgrade to the highest LEVEL which in this case is PRO1. In Post/Page Quotas Setting page i selected the minimum Pro Site Level required to Pro 1. and then in Products Quota -> Publish LImit to (2).
Then i go to the test site dashboard and entered 2 products and after it says that i have reach the limit. NB.remember that the test site is already in PRO1 level. should the limitation apply to the PRO1 or just the level that are lower than pro 1.
Don't know if you get what am trying to say.
