-- HikaShop version -- : 2.6.4
-- Joomla version -- : 3.7.5
-- PHP version -- : 7.2.5
-- Browser(s) name and version -- : Chrome, Internet explorer, IPad
-- Error-message(debug-mod must be tuned on) -- : Blank screen
Recently, something broke behind the scenes and now attempting to checkout with a "login" step in the workflow results in a blank screen. Logging into the site first bypasses the problem, as does removing that step entirely, however neither of these options are doable.
I would really rather not update HikaShop if at all possible. Any ideas?
