update 5.5 error

[xmanhattan]

Hello,
I set my site to offline and then updated the site to 5.5.
The process appeared to updated normally.
After it finished, I logged out and then tried to login but I received Login failed with error message Internal Server Error

I am currently in the process of comparing and analyzing changes to the template files to see what has changed.
I have a backup of the FS and DB.
I changed my configuration file manually to activate the site again.

If you have any suggestions, I look forward to seeing them.

Reverted to previous files then updated again.
Working now.

The process completed successfully on the first try? Did it show you a link to update the database? If yes and you didn't clicked that link this is why you got a fatal error. Elxis 5.5 has changes in database (especially in users table) and if you don't update the database you will get error.

As I remember, it completed the process but I did not see a link to update the db the first time.
I did see it the second time.
The first time I set the site to offline, on the second time I set the site to admin only.
To correct the problem, I restored only the files not the db.
Not a problem, it works like a charm.  Great work!
Thanks.
