Hello Sylvie,
Thank you for the query. Can you please state what’s the exact issue you encountered? If possible, please provide your site URL so that I can examine it in detail and send you the necessary fixes.
Additionally, Sylvie, the theme includes a portfolio pattern that you can use as a gallery, or you can utilize the default gallery block in WordPress. However, if you still wish to use the CatchGallery plugin, please share your website URL with me so that I can check it for you.
I regret to inform you that we don’t have a pro version of the CatchGallery plugin.
Regards,
Sujeet
