Project Description:
We have a Prestashop site at : The site appears to be running slowly especially on products which require multiple option selections. The main aim of the job would be to increase the speed of the site.
We also have an issue in which the invoice numbers are not setting to the required number... they simply default back to the prestashop numbering rather than the numbering we want although they do rise by one on each sale.
This job would ideally suit a prestashop expert. Price is negotiable. We look forward to hearing from you
