Within a page or post I can set a custom header image. This functionality is part of the theme that I am using. When I click on the button to upload an header image I get this error:
You don't have permission to access /wp-admin/media-upload.php on this server.
Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.
I renamed the .htaccess files to htaccess.txt in de root and wp-admin and the error disappeared. So this is related to BPS?
