Sales report 2.0

[FrenchFrog]

Does the Sales Report appear properly in the "reports" dropdown? If you mouse over the link in the menu, the URL should appear in the lower left of your browser. Does it have a valid link? Nothing like "STATS_SALES_REPORT" in all caps, right?

See attached screenshot, everything looks fine

Do you see the same behavior if you substitute another admin page for the Sales Report (e.g. orders page)?

all other admin pages work fine UNTIL I select the Sales report option, which blocks the entire admin by asking for a login on every page request. If i delete the zenadmin cookie, I can access the backend again

Is there any crossover--shared admin, products, etc--between your OSC and Zen Cart stores?

The databases are completely separate. Nothing is shared: no file, no table.

I'm clueless.

Thanks for your input!
