Isn't that an old except syntax that is not supported in Python 3?

I'm thinking it should be:

except Exception as e:

...but, I'm no expert in 2 to 3 changes. Anyone else know more about this?

The error seems to be in:

session_data = pickle.loads(row['session_data'])

try to delete session files or data

Leonel Câmara, told me delete all errors and session files when I change web2py version. As I think that can be useful in my situation. I deleted all errors in all apps and now don't see new errors. I will be wait and check apps errors tomorrow. Thank you, Jim S and Massimiliano.

I am having the exact same problem, removing session data did not help.

2.20.4-stable+timestamp.2020.05.03.05.18.50
(Running on Rocket 1.2.6, Python 3.7.2)

I downloaded the latest web2py source, the app I am running was originally in python2.7, however.

Are there any alternatives other than going back to the old python version?

I got several such errors in p3.

Changing to:

Except Exception as e:

Works for me.
