Trouble connecting to database since 4.0

I used 4.00 now 4.01 for the first time today and I am unable to connect to my database (with no changes) Now the site is down as no data is showing? Where do I start?

Do you have a link to your site you can share?

PASS Teams (pasprintseries.com)

Please enable debug mode as explained here to see what’s wrong:

looks like it was a password issue, not sure why but I’ll research later as I need the site running for now. Thank you
