I am using version 1.6.1.5 and need to upgrade to 1.7, but not having any luck. The 1-Click module gives the error: [Ajax / Server Error for action unzip] textStatus: "error " errorThrown:"Bad Gateway " jqXHR: " ". After searching multiple posts, I thought it might be server related. Our server, ipage, suggested that the php was not correct, so we changed it to a higher version, 7.1 or higher (don't remember which one exactly), but that crashed all of prestashop. Rolled it back to 7.0 to get the store back working. They then escalated my ticket and then sent me this email:
We are a small non-profit, so funds are very limited and so are my skills! That is why I am trying to do all this on my own.
Thanks!
