Hi there!
1 - gzip compressor in configuration not working with your template
2 - lazy loading not working as you said here
www.smartaddons.com/joomla-templates/use-lazy-load-to-speed-up-images-loading
3 - Merge file in extensions > sj shppy template sittings> advanced ... not working.
My hosting provider and also joomla team work and virtuemart forum.
they mention the problem is coming from the template and some other extensions as following:
sj super categories
sj vm deals
sj mini craft pro
ytshortcodes
So what is the relation between this errors and jch????
it's clear ... you should solve this problems for me because the template need to meet joomla standard functions.
I know what I'm talking about and I'm using joomla since version 1.0.13
So when you acknowledge that your template doesn't meet joomla standard functions and you solve it seriously then you gain more respection
but when you sale product that make wasting time of customers that will make your reputation very bad in the market.
All what I'm waiting to hear from you that your team will do their best to help and solve all issues ... that's if you care about your products.
Thanks
