We have Open Cart website version 2.2 (I think) mostly works just fine, has a template in place.
A couple of things have come to our notice, which need to correcting please;
1. The Quick Look popup which is available when rolling over the product shows as blank when clicked. NB: this did used to work, definitely, not sure when this stopped being the case.
2. At checkout when you try to change the quantity amount of a product and click refresh you are taken to a blank page with just  on it? Please see image attached.
Happy to pay $20 each for these and no more, I know they are small changes, so don't bid more than $45, you will be deleted, and frankly it proves you haven't read the description.
We have 12 other website on various platform and need reliable Freelancers to help, there's always issues coming up, be helpful, honest and reliable please.
