I run Prestashop 1.6.11 and have 4 problems that I cannot resolve on my own and would need support.
1. I enabled SLL on my shop about 3 weeks ago. Since this, the "Save and Stay" button doesn't work 2 out of three times. It just goes back to the product listing without saving any changes.
2. I sell products that have a tax rate of 7% and some that have a rate of 19% rate. By mixed orders, the shipping needs to have a weighted average tax rate and I believe this works. However, the netto amount of shipping needs to be split accordingly between then 7% rate and the 19% as well and this does not work.
3. I installed a module to help me customize my invoices. Ever since this installation (I think that caused it but I am not sure), the text is my dashboard is blank, but I see the statistics.
4. When reading the product category on my page there is a "More" button that shows all of the text. I also need a "Less" button to hide it again.
