Hi,
After the active ( Base 64 encode for placeholders ) option in Lazy loading, the default woocommerce placeholder image does not work. This bug is only for default woocommerce placeholder images.
for default image link is src=”image/jpg;base64
for other image link is src=”data:image/jpg;base64
Woodmart 6.5.4
Theme Settings-> performance-> Lazy loading -> active
Theme Settings-> performance-> Lazy loading -> Base 64 encode for placeholders -> active
Please deactivate all the plugins except these ones:
Slider Revolution
WPBakery Page Builder or Elementor
Woodmart Core
Contact Form 7
MailChimp for WordPress
WooCommerce
Safe SVG
If you use the child theme, deactivate and check.
If the problem has gone, activate the plugins one by one, checking the issue to detect which one causes the problem.
