We have recently upgraded from zen-cart 1.5.0 to 1.5.6b. Site is operational but a few things such as Easy and Fast Checkout, Easy Populate, Payment Modules etc. have been acting up. We are willing to keep some modules/plugins but upgrade them to cooperate with the new version and get rid of some that we longer need. We need a really experienced zencart freelancer for this project and if all goes well for long term business relationship to help us with several other zencart sites.
