Sorry that you are experiencing issue
Firstly are you able to post a link to your website, to check that nothing is wrong on the Front-end.
Secondly before proceeding could you make sure of the following:
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.
If using a WordPress Cache plugin, disable it or clear your cache.
License key not activated - (in website blank situations or button not available)
If your WordPress Dashboard shows a warning "PHP Update required”
Please update your PHP version in your webhost control panel.
Possibly your website is running PHP 8.0 this has been known in some cases to cause issue.
Talk soon Quentin & have a wonderful day 🌝
If we cannot find the issue easily then there are options for me to Login and check or worst case install a previous version (3.8.4) if the Bug relates to the new (3.8.5) version of Lay Theme
