After upgrade to 4.2, seems my cart is, not functioning. Everything else appears fine!
 
Please read on...!
 
If I log into 'viart Control Panel', head to 'Orders/Call Center Orders' , it shoots me to basket page, and 'add to cart' via pop out 'Products link', works for adding products to cart. Naturally as, 'admin' and in that view, that's expected. Right?
 
General 'Add to Cart' on website for any user however, does not. Did a 'switch' get flipped somewhere during my upgrade that doesn't let casual users add to cart on the site? Seems the function to add to cart, at least from 'Call Center...' is there, but not for 'products_details.php' , on public facing?!?
 
This seems like I'm missing something pretty basic here. Having tried to follow the php, I can't seem to track down where, and why it's failing.
 
Any info, or hint, would be appreciated. Not afraid to get my hands dirty, but I know many of you know this code far better than I.
 
Thanks for your time, and any help you can give insight on!

Made some discovery, but not quite what to make of it. So, this site has 2 other subdomains, but neither have this specific issue.
 
For intents, the site has the following:
 
www.test.com
- "Add to Cart" link displays as '#' sign - does not add product to cart, and dumps to Home page instead
 
www1.test.com
- "Add to Cart" link displays as '/products_details.php?cat(...long string here...)' - does add to cart
 
www2.test.com
- "Add to Cart" link displays as '#' sign - does add to cart
 
First off, I think intended behavior on the site is supposed to be the '#' sign for the 'Add to Cart' function, correct? Where in viart/db, would this change be per subdomain? I thought this was a global setting?
 
Second, www2 products, doesn't use /product_details.php for its page listing with 'Add to cart' option. Uses its own page, where as www and www1, use /products_details.php , when at 'Add to cart' ready. Not sure it's relevant, but I noticed.
 
In addition to www2 doing that, upon 'pop-up frame' of cart, doesn't seem to be using formatting that www1 is using for same content. Also missing some block content on standard products page of www2, which tells me isn't quite 'set up' consistently like www and www1.
 
Obviously there are inconsistencies going on, but I honestly am not sure where they're coming from. Are these problems both Global, and 'Site' specific that are inter-mixed? I've tried to locate inconsistencies between the sites, but haven't found much.
 
As always, any input on this is appreciated.
