Every ReviewX plan caps how many separate WordPress sites you can have actively connected at once — this is what “site limit” or “activation limit” refers to across the Client Portal.
How it works
Each license key can be activated on one site at a time. Your plan determines how many license keys (and therefore how many connected sites) you’re allowed to generate — higher tiers and the Agency plan allow more.
What happens if you hit the limit
You won’t be able to generate an additional license key until you either upgrade your plan or free up an existing one. See Managing Your Licenses & Connected Sites for how to remove a site from a license you’re no longer using.
Moving a license to a different site
You don’t need a new license just to swap domains — remove the old site from the license in the Client Portal, then activate the same key on the new site.
