The link to download the latest version of Relevanssi Premium appears below if you have an active subscription. If you don’t have one, register for an account here and follow the instructions.
If you’re looking for the free version of Relevanssi, check the WordPress plugin repository.
If you have canceled the recurring subscription in PayPal, you won’t be able to download the plugin files from this page. I’m sorry about that, it’s a problem with my membership management plugin. WordPress auto update downloads will work, and if you need the files, just drop me an email to firstname.lastname@example.org and I’ll email you the latest version.
