Upgrade 404 error

I am trying to upgrade from 2.0.14 to 2.0.15.

It checks my cart and says it is ok, and closes the store, but when I click continue after a while I get a page 400 not found error.

i am pretty sure I have not changed any settings that should affect upgrades.

Any ideas anyone?

cs cart want 20 credits to look at this, Help…


For 400 error, it shall say which php or tpl page is missed. Just manual upload that page from CS-cart archive.

If you don’t have any idea, give us your site link.
