OK I was having issues where on every article page the metadata being used was the global metadata even though I had metadata added to the articles two metadata fields.
I ended up finding it was being caused by the 1.6 metabot installed with 2.2,6 of Joomsef that was causing this as when I unpublish it the metadata for the articles are now correctly shown. Is this what it is meant to do?
I tried setting all but the 'prevent site name duplicity' to no but that still stopped the metadata being shown correctly so I have had to turn the metadata bot off.
Anyone else having issues with the Joomsef metabot and yes I have tried an unsintall and re-install
Cheers
