On the cart page, if a returning user logs in, the bill to address is not populated, however if you login through "Account" on the menu bar it does show the address. Running 2.0.26d and Joomla 2.5.14. Tested with and without caching enabled. Also tried it with the beez template, same results. The URL is www.wildbirdhabitatstore.com.
thanks
Please update your joomla asap! and please try the latest vm2.5.x, thanks.
I did update to 2.5.18 but that did not fix the problem.
thanks
