I used it with this plugin
Post Grid Gutenberg Blocks and WordPress Blog Plugin – PostX
https://es.www.ads-software.com/plugins/ultimate-post/

But when creating a template with nexter builder, and using postx it does not work, it loads all the entries in a single row

However, if I create a normal page with postx , postx works fine, so it must be something from nexter builder

I think the styles are not loading correctly or something like that

Nexter Versión 3.1.3
