Hi Anna,
Thank you for the feedback.
1) It was PMP Pro Register Helper Add on plugin that was causing trouble. I have desabled it and everything works fine now.
2) Vendor can fix shipping fee. But i would like to add the local post office (Colissimo) plugin that calcultes shipping charges and allow tracking the order. I would like buyer to have choice between vendor shpping method and charges and “Colissimo” shipping charges.
Concerning the 5th point, i have not got it. This plugin is for which problem?
3) As you can see in the screenchots, description bellow fiels are moved to the right. And are not visible. How can i align to the left an remove the black background?
Thank you for the help
