I've upgraded web2py version from 2.0.9 to 2.8.2.

Is this the reason of the error?

Because of the error, I cannot check errors during using web2py. Please help me....................................... T T

Do you guys know solution or reason of this error?

Or Is there any other way to check error tickets instead of using the admin app?

Thank you for your answer =)

just delete all the "old" errors and you should be fine. The problem is that the storage format for errors changed in a recent release, so the "new" web2py can't know how to open error files created the "old" web2py.
