So I decided to upgrade my wordpress installation on my company intranet.  We were running an older version of WordPress MU (2.7..so I thought) and wanted to bump it up to the latest.

I read the instructions over and over and seemed pretty straightforward.  So I began.

Step 1. Tar up my site.  That took forever.

Step 2. Dump my db.  Did that.

Step 3. Script my db as well.  Glad I did that.

Step 4. Back up .htaccess and wp-config.php and copy over all files (not wp-content).

Everything was going well.  Checked permissions, files, db…all was in order.

Fire up my browser and nothing.  I looked at firebug and saw that i was getting a 500 error.  Checked the logs nothing out of the ordinary.

Did the following: login with the db user using phpmyadmin, mysql, changed password, created new user and nothing worked.  I then created a new db and copied tables over…nothing.  I then tried to start from scratch..kinda like a new install…nothing.  Still could not connect to DB.  CHMOD 777 everything.  Nothing.  Finally I downloaded another 2.8.4a version and uploaded the whole thing.  New installation with that went fine.

Argh.  Tried to change to old db, nothing.  So I manually copied over all the data into the new database.  Still doing it.  Also, my theme no longer works…that is Fridays job
