We currently have installed Prestashop 18.104.22.168 and we installed a template to run only for this version. Everything is working fine at this moment.
We upgraded to Prestashop 1.4.3 and the template is not working properly. Most of the features are not available. So we needed to go back to 22.214.171.124.
We can upgrade to 1.4.3 with no issues but what we need is to have the same template that we have installed with all current functionalities working as when we were in 126.96.36.199 and being able to add the new features coming with Prestashop 1.4.3 like product comparison, etc.
Please how much would it cost and how long would it take?
Looking forward to hearing from you.
