Dear @matous
Are you able to provide any further information about your setup, screenshots of back-end etc š
Please make sure of the following when debugging your Lightbox issue:
Wordpress, Lay Theme & Laytheme's Addons are all up to date ?
Any custom CSS or JS that may interfere is temporarily removed.
Any third-party plugins are de-activated to see if this resolves the issue.
Talk soon & best wishes š
Richard
