I have been receiving the horrible old message:

"You are not authorised to view this resource You need to login"

This has been occurring when I've been using Joomla 1.0.15 and the myContent Component! version: 1.1.13 to enter new content from the front end.

I have a module, mod_latest_created_updated_date, which shows a list of the most recently Created or Updated Content Items

This module works correctly for any item created using the normal methods displaying each item and linking across. However, when you create a content item using mycontent the link shown by mod_latest_created_updated_date shows : "You are not authorised to view this resource You need to login"

All other links working fine, just the new links in this module created using mycontent were adversely affected.

I have tried to analyse the content, the URL's generated but initially no solution found.

Then I looked into the Artio configuration: and tried to find something that might affect the problem, changed this config. item.

Do not remove SID from SEF URL? to 'yes', cleared all caches, then the problem went away
