Reply To: The photos sizes in gallery under the single post are not equal

Hello,

Most likely, some plugins affect the images so I suggest deactivating all the plugins except these ones:

Slider Revolution
WPBakery Page Builder or Elementor
Woodmart Core
Contact Form 7
MailChimp for WordPress
WooCommerce
Safe SVG
Please switch to the parent theme if you use the child.

After that, check the issue again, if the issue still persists, please confirm the permission for the plugin’s deactivation, switching to the parent theme. As soon as we complete the testing we will enable all back

Kind Regards
