Hi guys,
PHP Version 7.3.8
Joomla! 3.9.11 Stable
VirtueMart 3.4.2
Template Vmbeez3
As stated in the subject, BOM is added to the cart module and shift the module content down.

Same issue with Horme3 but only when an item is added to the cart.
I checked with notepad++ that the files involved were correctly encoded in UTF-8 and not with UTF-8 DOM. First suspects were index.php and mod_virtuemart_cart/default.php but they come out clear so no luck with that. Furthermore that doesn't add up with the fact issue is only in category view and home page.
I cleared the browser cache and joomla cache, tried different browsers but issue persists.
I'd be glad if you guys could check if you have this BOM marker in your code. it is invisible but can shif content down and is displayed as red dot in firefox developper console. In google developper console it shows as "
"
I suspect the issue comes from the ajax script updating the content of the module but couldn't locate it so far.
Community help is greatly appreciated.
