plugins not working on buddypress 1.5.1

I am trying to rebrand the site and most of the plugins not working when stating works with buddypress, global footer content, login image, new site generator rebranded meta widget, etc.. I got the error message "The Global Footer Content plugin is only compatible with WordPress Multisite" and had to delete the plugin for wordpress to work again.

The pro sites plugin not working either, I dont see any menus.

Please advise.
