I want a refund and stop membership for elements. Themes have no stylsheets and plugins are not valid
Just a tip, but when dealing with open source software and encountering an error, searching that error on Google can probably help you figure out what’s wrong.
In this case, you’re probably uploading the wrong files. Themes come with documentation in a zipped archive. You need to extract the archive somewhere on your computer, and inside you will find one or more .zip files which should be uploaded to WordPress. The same goes for plugins.
In fact, this error is even covered by the Envato Elements Help Center… which would also have come up on Google. See: https://help.elements.envato.com/hc/en-us/articles/360000629466-How-to-Install-a-Theme-on-WordPress#missing-stylesheet
While a refund is unlikely once you’ve downloaded things with your membership, you should open a ticket at https://help.elements.envato.com/hc/en-us/articles/360000629486-Submit-a-Support-Ticket
