Popup Gallery problem – open 2 fancyboxes with the theme OceanWP

Hi !

Since I switched to the Theme OceanWP, I have a problem with the popup gallery. When I click on any image, there are 2 fancyboxes that appear instead of one (one fancybox shows the image itself, and when I close it, there is another one with arrows. I want to keep only the one with arrows).

I think it comes from a conflict with my theme because when I activate other themes like Twenty Nineteen, there is no such problem. I want to keep that theme, do you have any idea to fix that problem ?

My current WP configuration:
– WordPress version: 5.2.2
– PHP/MySQL version: 7.2.19 / 5.6.43
– Theme used: OceanWP
– URI Theme: https://oceanwp.org/
– Plugins : Autoptimize (2.5.1), Beaver Builder Plugin (Lite Version) (2.2.2.5), Contact Form 7 (5.1.3), Duplicate Page (3.8), Forum_wordpress_fr (4.2), Ocean Extra (1.5.10), Really Simple SSL (3.2.3), Smart Slider 3 (3.3.21), Smush (3.2.2.1), Sticky Menu (or Anything!) on Scroll (2.1.1), UpdraftPlus – Backup/Restore (1.16.16), Visual Portfolio (1.13.0), Yoast SEO (11.7)
