Image issue on update to joomla 5

Hi,

I can see that you still have the image tags:
i.imgur.com/ldi0f1j.png
However, the URL of the jpg image is moved to a data-src attribute instead of the normal src attribute, and instead, there is a transparent SVG image in the src attribute.
I think this comes from a third party extension as there is no such data-src tag in HikaShop.
Or you have some view overrides doing this.
So first, I would recommend checking the plugins of the group "system" via the Joomla plugins manager.
Also, you can try renaming temporarily the templates/YOUR_TEMPLATE/html/com_hikashop/product/ folder via FTP in order to rule out view overrides.

Hi,

To optimize JS / CSS and other things, I think it's the best. JCH Optimize does wonders, but it's indeed tricky to configures so that it doesn't cause problems.
For this problem, if it comes from JCH Optimize, I would recommend contacting the support of JCH Optimize. It looks like a bug to me.
