powerCMS page update problem
On my powerCMS site when I attempt to edit a page then select "update" I get this reply.
"Not Acceptable An appropriate representation of the requested resource /admin/contents_update.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."
The powerCMS site has been working problem free for three years. The files/path have not changed or moved, they are on the server in the admin folder. This issue just started a month ago. Some pages will update while others will not. Please advise.
Thank you, Bob Blandy
