Incorrect value for expire days: 2037-12-31

I get the above message in red when I click on a signup verification link in email.
Please advise as to what this means?

I am having the same issue.

I setup a recurring monthly lifetime subscription package for members with the initial 1 day free trial and then from the backend added myself as a customer (as a test)... when I received the welcome email, I clicked the link to complete the transaction $0...and it gave me the same error message as above.

How do I fix this?

Please help! I assume its more urgent I get this going than it was for the last guy.

I believe I have figured out the issue. I had the membership set to lifetime recurring (this would obviously make no sense).

Instead I changed the duration to 1 month and selected 'recurring'. It seems to be working alright now.
