i been waiting for an answer to the question on the second paragraph and its a bit urgent, if you or know someone who can provide a quick response, i'd really appreciate that.
I deactivated all plugins except pro sites. cleared all cached, and use the default WP theme to test it nothing works for me. but i find the problem about the 404 error. it was a function in theme caused it.
can you please send me an outline to as where the pro sites plugin options is located in the database, i already find the pro sites default tables and the options name. Reason why is because even after deleted the tables and reinstall it, am still getting back my previous settings.
NB.I will let you know my results
