I have activated the BPS pro plugin in the main site. My site is Multisite.
When I executed the setup wizard in subsite, “Sorry, you are not allowed to access this page.” show up.
How can I activate the plugin in the subsites?
BPS Pro is activated on the multisite Primary site ONLY. When you activate BPS Pro on the Primary site all subsites are activated. A multisite website is really only 1 WordPress site that has virtual subsites.
