Sorry, did you log into our website? I AM using the templates.
But the link you sent did help me figure out what is broken: it’s the navigational URL.
In the gallery you sent me I can see the gallery’s page 2 link is: https://themes.themeregion.com/playbit/demo1/gallery/page/2/
But when the gallery page “2” link on my site is: https://www.mahea.com/collection/photos2
Based on your gallery, I tried this link: https://www.mahea.com/collection/photos/2 and it works. The gallery is not written correctly in the theme’s code. Can you please help me fix that?
