I am having a problem with inserting single photos into my web pages. I have the File Gallery plugin installed. I click Upload/Insert, select the file from my computer which seems fine. When I click Update, I get:
An appropriate representation of the requested resource /dev/wp-admin/post.php could not be found on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request."
I have tried adding a .htaccess file with SecFilterEngine Off & SecFilterScanPOST Off. I have also tried disabling all the plugins (except TinyMCE, jquery Lightbox, Capability Manager & Role Scoper which are essential).
The website is in development and exists under a sub-directory called /dev. Any ideas folks?
