I ran bench update now I cannot access my site. Some help needed

I ran bench update on my site, because it had some errors running bench run-tests and now I can’t login to my site. There are no errors in logs/web.error.log. The bench update was successful until my own site which errored out. Can someone suggest a debugging idea ?

Did you check the OS language before writing the password?

What’s the error?

That’s the thing, cannot see any errors. I just cannot login with the username / password.

Can you run bench update again and share the error trace

myapp is my own app that is not put in any repo.

I think you installed myapp in a site and that app has problems.

What would the best thing to do to get it to work ?
