I am trying to buy the basic site plan to add my domain, but its not possible to choose this.
Anyone know why?
Because you probably have a collection.
Collection of projects? Do you know how I can fix this haha
If you’re using a theme or created a new project that has one or more collections, you’ll need to remove those before you can choose the Basic Site Plan. This involves disconnecting any fields or lists that the collection is referenced within, then you’ll be able to remove the entire (empty) collection under the Collections panel.
This can be a bit tedious if you’ve got a lot of connections on the site, but Webflow gives you a quicker way to locate and delete them:
Hopefully that helps
