Has no one an answer for this problem? Other wise i must choose for another oscommerce system. It is getting time that the makers of abantecart get more knowledge to solve problems.
I think this post shows the challenge deploying any app or webpage. One word of advice I'd recommend is if you are running into a problem and no one else posts about that problem much or at all, then it's most likely only affecting just YOUR configuration.
It's not so much no one wants to help you or the developers don't care...but since it doesn't affect them or anyone else, they don't know or simply can't recreate your problem so they have nothing to go on...
Choosing another platform or any platform (doesn't matter) won't help because if your config wherever you're hosted at is messed up, no commerce system will matter at all.
I was running into a strange problem where I couldn't even install a vanilla install of Abantecart (still not sure why), but it's probably just within my hosting provider's config...Very much a pain, but not much anyone can really do (without spending more time and get possibly dedicated hosting or root access)...
Also, can't figure out manual upgrade at all and assuming that I am the only one in Abantecart land looking to do that.
