Hi Randy,
Thanks for reaching out and thanks for using Crio Pro WordPress theme!
Often times when issues suddenly arise it’s tied to another recent change on the site. Have you recently installed or deactivated any plugins? You sometimes noticed these issues after an update or they could also indicate the need to update. Did you notice the issue after updating your Crio theme, a plugin, or WordPress itself?
If you can you send us the URL to the gallery page you’re having trouble with, it’s possible we can inspect the page and find some clues as to why this is happening.
I hopes this helps! We look forward to assisting you further with this if need be.
