display logs title issue

okay, doing a default install on the original database with NO custom template - leaving it to show the template default does not stop this issue.

It's not a template file, it's not an errant old file. The only left is the database but I can't see how anything there can cause these warnings. Maybe this is just an odd happening - over the years I've seen a lot of strangeness from an old database and I can certainly give the cart owner instructions just to the error logs regularly - for me it's really a great indicator for some clients do some cleanup or easy maintenance.

But as we are dealing with the new version, I think we should go deeper into this and I'm at the end of my ideas. Shall I just let this die?

Check the database's configuration table for any configuration_key value(s) that are equal to TITLE.

one - same one I use on every site. No issue on previous 3 upgrades.

Look through the database's admin table for the values in the reset_token field.

Each field should be either an empty string or a string that looks like nnnn}aaaa, where nnnn is a string of numbers and aaaa is a string of alphanumerics. The connecting } is required and is, most likely, missing ... which is your underlying issue.
