OK. I ran the sql patch by simply logging in to MySQL, "use" ing the relevant database and copying and pasting the text file directly into the command prompt in one go -it processed it line by line. This is just for information for MySQL newbies! I'm not that proficient myself but I couldn't figure out
quickly how to get PHPMyAdmin to run the patch
..
Anyway, all seems well. I now have the "enable https login" tickbox and whatever else the sql patch was meant to do. Is there any reason why this sql patch failed when I applied the whole 3.5.2 upgrade from the GUI, yet worked when I applied it separately? Aside from the func.php giving me problems, the sql patch was the only other problem.
I was also sent another sql patch from the X-Cart team regarding reinstating the Fulfillment membership option for order processing. I don't think this is enabled by default on 3.5.2. That now works fine with Administrators flagged as Fulfilment Staff only seeing the orders section when they log in. This is starting to become a productive day...
