This is really strange.
I have a multisite installed and Membership on both subsites.
I have configured intelqube.com successfully but for intelqube.com/es the wrong content is being blocked.
Both sites are identical, the only difference is the language.
I have one free membership level and a visitors level.
When logged out from the site (intelqube.com/es) it will block the blog, login, register and contact pages.
I have a negative rule on Visitors level that block the member pages (top menu), the rest should be visible.
