admin login as customer suddenly stopped working: Whoops! Your session has expired.

ZC Version: 1.5.1

admin login as customer suddenly stopped working:

This is what I see: Whoops! Your session has expired.

This works on two other sites just fine. It stopped the opther day. Any help is appreciated. Thank you.

When this has happened randomly to clients of mine, something changed.

Typically it's a server side change. Maybe your host updated cPanel or your SQL or PHP versions.

Maybe a file got lost or overwritten in the process... unless you were making changes?

**Troubleshooting:
**

• Check for error logs that may point at the problem

• Check for any changes that are not ZC 1.51 compatible on your hosting account

• Compare core admin startup files against a working backup or original Zen Cart for anything out of the ordinary

• Try logging in with another browser

• Clear your browser cache, try again

Thank you for the reply. I figured it out. I uninstalled a plugin but did not disable the sidebox. Once I disabled the sidebox everything works fine now. Thanks for the feedback.
