Hello @klelietta,
I checked your site dashboard. It seems that you are not using the Image element of Gutenberg, you are using the Gallery element of Gutenberg. Please have a look at the given screenshot below.
I have also noticed that there are some JS console error and Mixed content errors because of that the Gutenberg column style is not rendering on the frontend.
I tested in my local test installation it is working fine and the Gutenberg styling in rendering because of that the image in the two-column displaying side by side.
Local test site screenshot.
I would suggest you troubleshoot with a few of the common issues before we investigate your settings.
- Testing For Theme Related Issue
- Testing For Plugin Conflict
- Theme Update
- Child Theme
- Css/Js Customization
- Increasing Php Memory Limit
- Disabling Cache
- Disabling Cdn
- Permalinks
- Version Compatibility
If none of those work, It would be best if you could copying your live website to your staging area. and send your details in a secure note so that we can investigate your setting without breaking your live site. Please provide the following details
- WordPress Login URL
- Admin level username and password
- FTP Details
You can find the Secure Note button at the bottom of your posts
Thanks
