Hi,
I found my error message in a couple of posts, but none of the answers helped me…
i recently installed wordpress and installed X theme over the .zip upload option.
I activated it successfully, but when i click “LAUNCH” under the X in wp-admin, i can only download the x.zip.

When I want to use Cornerstone to edit a page, i get the “The requested URL /x.zip/ was not found” error.

Thanks for your help.
