Well, please don't take it personal, but if you really plan, to get this Shop to work as planned,
you'll need a 'top class performance' Server. In addition to a top class Dev, to 'combine' that
giant amount of JS + CSS Files into a couple of Files only, to avoid, to have that great
big bunch of them 'called' individually during a Pageload.
---
And the Source itself needs to be 'output-compressed/minified', to avoid all those good-for-nothing
empty lines on an HTML Page Source, as existing in your Theme Source Files:
https://www.opencart.com/index.php?rout ... _license=0
https://www.opencart.com/index.php?rout ... _license=0
---
In addition to a few small Modifications, like COOKIE-FREE JS / CSS / and Image Linking:
viewtopic.php?f=20&t=155085&p=759255&hi ... ge#p759255
viewtopic.php?f=198&t=220697&p=804775&h ... ge#p804775
viewtopic.php?f=190&t=205407&p=749031&h ... ge#p749031
to unleash most all Brakes, and so enabling a Server, to 'handle' the Code in the speediest and so most effective way.

Plus an
.htaccess file, automatically
redirecting anything else on access links than:
https://www.eatr-mekyag.com/ ......... -
https://eatr-mekyag.com/ ......... - or whatever,
if you really have it configured this way......

, it was nearly impossible, to find out on this, my
Browser mostly cannot even load that Site in full. If configured wrongly, and/or not 'ordered' by
.htaccess, parts of your Content will most likely not show up, because linked differently
by CONFIG default.

It's the price, to pay, to get a Theme, obviously filled up with everything possibly and available,
by some SO-Theme-Coder Freak, trying, to find out, how much it takes, to reach the performance-
limits of a low-cost 'shared Server' environment.

Sorry for the bad News ! One should always have a good/close look under the 'Outfit' of a future
'Partner', before one decides on getting married,

and the same applies to Internet Layouts.
And if one checks a Webpage by use of the
Page Source Browser Function, one can easy find
out, how
near or
far such Code is, in comparance with a 'default-like' styled and coded
Theme Source.

Whatever you decide on, something needs to be done, or you won't make it. I'm sure, one of the
known Coders here could help you, but it would by far exceed free Support, just be aware of that.
Good Luck !
Ernie
PS. And better be aware, that 'regular-OC-themed' Extensions most likely won't work within
this Theme, it's too far from OC Default ...., just in case !
