Only one column

Update to latest version of this plugin, please.
Make sure the latest CSS is served (thus cleaning any caches).
Provide URL to your test installation to allow to check it.

Still not working..
Here’s the URL: https://www.juditpolo.com/test/

I get errors on that URL.
Have you tried different themes? I’m pretty sure this problem is not seen with every theme cause it works as it should on development and testing installations. There is no such error known. I can’t reproduce the problem that you describe.

Will try your URL later. Please try to keep it up and running for test purpose.

You are right, I don’t know why there where errors, I deleted that URL.
Try this now: https://www.juditpolo.com/test1/
Still only one column but no errors in the URL.

Thanks for the test URL – worked this time.
It looks like the wrapper DIV from your theme is not wide enough to allow multiple columns.

Try to set columns to 2.
If that does not work use smaller images.

Last but not least try another theme temporary – should should see that with a wider wrapper around the gallery more than 1 column will be possible. Hope this helps.

I also confirm that there is a glitch with some themes that makes it impossible to use multiple columns. That’ something that will be improved with next version – but that might take some time. Thanks for your patience.

Try Version 1.2.1. Should solve your problem.

I updated the plugin, and it’s partially solved.
Now I can see more columns but it makes a stairs effect as you can see here:
https://www.juditpolo.com/test1/
What can I do to solve this?

I can see paragraph tags in the html of the gallery that was NOT inserted by the RFG Plugin! They do not belong there.
I have not seen those before. Not sure if they come from your theme or another plugin that makes a preprocessing before the html code is send to the browser.

You could check if you have plugins that to changes to your html code.
Maybe you can try another theme – just to identify the root cause for the paragraph tags. I can’t reproduce the problem here – tried with default WP them “Twenty Thirteen”.

Let me know what causes the insertation of the paragraph tags.
I guess you have a plugin that changes newlines to paragraphs and br tags…
