Site is learnenglishontheinternet.com - have two galleries on home page and had no problem with two rows of images displaying as uniform thumbnails squares. All images are different sizes now and are not responding to changes in Elementor page builder. Thanks for any help!
You should have to use a tiled or grid gallery for that purpose.
Have an excellent day
Do you know why the gallery would have been working fine for the past months up until today? I am using Elementor and had no problem with the grid before.
To confirm whether it is an Elementor specific issue, try switching the theme to one of default WordPress themes like Twenty Twenty and see whether the issue remains or not.
If it remains there, you may want to seek for help on Elementor’s community support based channel.
