Hi,
Thanks for that.
So the issue, is linked to the update and the javascript error you reported.
The issue comes from the javascript code:
$('#g-sidebar div.hikashop_filter_main').html(function(i, html) {
return html.replace(/\:/g,'');
});
of the file
test-abierto.ofertaexportable.net/templa...x/js/template.min.js
from your template.
That code will remove ":" in the whole HTML of the filters area.
And with the latest version of HikaShop, we've moved the javascript of the filters from being in the headers of the page to being along side the HTML of the filters to simplify the AJAX loading of the filters and also for the Joomla 4 compatibility.
And thus, the javascript code from the template is now breaking the javascript code of the filter system, generating that error.
And since your template hides the whole content of the page until the page is fully loaded and then displays it at the end of its javascript, and since your template's javascript stops in the middle because of what I explained above, it stops before removing the white cover on the page, letting you think that the page is not loading at all.
So remove that javascript code from your template js file and it should hopefully work. Also, please report the issue to your template provider.
