Sleeper - my Joomla would not "discover" com_tags either - THANK YOU FOR THIS! It was the only answer that fixed my com_tags problem.

Also - I looked right at the db 'extensions' table. "com_tags" is simply not in there.
Where do I get tho mysterious extension? I looked via FTP in 'components', and the files are there!
So what to do? Manually add the db entries, because the files exist? Delete the files and see if the admin recognizes the need to install? (I will back up the folder, naturally)
If anyone could post the row from the extensions table, containing the com_tags…
PHEW! - I added the data to the extensions table, and the error went away.
