WordPress Plugin doesnt work on my theme

Hi,

I purchased a wordpress plugin from themeforest which was https://codecanyon.net/item/media-grid-wordpress-responsive-portfolio/2218545 but this plugin doesnt work with the minicorp theme. I tried the plugin on a different theme on my site and it worked. The plugin is on my page listed here https://www.snappanel.com/connectors/ which there is something in the theme that is preventing the gallery to extend out all the way. it shouldn’t be that tiny on the page. I talked to the developer of the plugin in and they said its from the theme, and i did test it and got the result that it is from the theme. Please Help!

Thanks,

Sevada
