Hello, @ecabral
Thank you for your interest in the plugin.
The Free version allows you to filter any Post type, but on regular WordPress archive pages. That is, if you want to filter WooCommerce products, for example, you can do it on the Shop page and on the Product Category or Product Tag pages etc. If you want to filter Posts, you can do it on the Blog page and on the Category or any Archive pages.
However, if you want to filter on singular pages, where you can usually only display posts or products with Page Builders only, which are paid for, you have to use the PRO version.
Therefore, the logic is simple – with the Free version of the plugin, you can filter what is displayed in WordPress by default. And with the PRO version, you can filter what is displayed with the help of paid plugins.
If you have any questions or you can not configure the plugin, please let me know or you can aks us in the support forum. We usually respond immediately during business hours.
I would be very happy if you change your revuew. It gives us inspiration to improve and develop the plugin and make it better, easier, more convenient.
Thank you for your understanding.
Best regards.
