Question An invalid post ID was requested - Read so many threads, no solutions?

Hi all.

I recently migrated our Joomla site to a new, upgraded server. SInce then (i believe) when I try to go to posts it says An invalid post ID was requested.

Test it here - www.marketingwonders.co.uk/forum/introdu...iness-in-here-2.html

I have just upgraded from 1.5.22 to 1.5.23 and now there is an internal server error showing at the bottom.

Please advise, I have read COUNTLESS threads today on the invalid post issue and none of them offer any suggestions.

Our configuration settings are:

Database collation check: The collation of your table fields are correct

Legacy mode: Enabled | Joomla! SEF: Enabled | Joomla! SEF rewrite: Enabled | FTP layer: Disabled |

I should add that I get emails when new posts are made and the link in the email also takes me to this error.

Hello,

i advise you in a first to disable legacy mode and enable debug mode in Kunena configuration panel to see a more detailler error
