Bug!? Visibilty issues with StudioPress theme…

I’m creating a website for my friend/date and her law company.

The site is still not finished yet since text and some images are just poor examples… However, I having a hard time getting the slider image visible EVEN if it’s visible sometimes (or when you read this post) IT seems like it gets visible sometimes when I’m changing the image size… So I have to change image sizes and refresh multiple times before it gets visible. Sometimes I even has to create a new post.

Those are examples of plugins I use:

Ithemes Security Pro
WP Rocket

I guess those might have an impact… I’m also using a subscription with Stackpath CDN. But I tried to clear the cache (both using the plugin and the CDN Dashboard) and deactivating all plugins. The visibility problem still persist…

This is the Framework and the child theme:

– Genesis Framework
– Executive Pro

And the “Executive Pro” theme has a built-in support for you plugin. So, I wasn’t sure if I should get in touch with StudioPress.com directly thought a ticket, but I’m trying here first…

So… What do you say? It looks like a bug to me!?
