I have found a few threads on this but none with any answers... After a customer logs in it takes them to the home page - from what I have read it should take them back to the last page they were viewing.
I have a fairly new installation of 18.104.22.168, and tha only mods I have installed so far are:
* Froogle Feeder
* Google XML Site Map
* Froogle File Genorator (which I don't use anymore & can uninstall)
I have also customized a few templates (mainly product pages)
but I am wondering where to start troubleshooting this error.
