Re: Upgrade Errors: It looks like your database is out-of-date.
Day two of attempted upgrade.
I combed through the boards, without much luck in terms of issue resolution (gripe!). If I figure out the remedy to my issue, I will be sure to post it here (so we can benefit from my stupid mistakes). 
I re-read the upgrade directions, and thought I would give it a fourth try. This time, I restored my 0.9 install and files, logged into the Admin control panel – everything okay.
I then moved all the new 1.0.2 directories over & replaced the 0.9 files (since I knew my backup worked). I verified my bb-config file was still good (shouldn’t have been touched).
I then ran the ‘upgrade.php’ script forum/bb-admin/upgrade.php
and got the message that my DB needed upgrading – so I select ‘upgrade DB’ and then receive:
ERROR: Could not establish a database connection
So – if I’m able to login to my bbpress 0.9 install and have full access to the DB, and I’m using the same bb-config values (same file!) – why would I not be able to establish a DB connection?
BTW – in another post, someone mentioned clearing browser cache helping…which I did. Nothing positive…
Any ideas out there?
