Dear @Sunnyi
Please make sure of the following debuggings:
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.
Additionally take a look at https://laytheme.com/troubleshooting.html
for known problems.
If these do not help:
Could you please send your website address, /wp-admin/ username and password and a link to this topic to info@laytheme.com?
Is likely a Bug & will try to get it sorted as soon as possible.
Apologies for any inconvenience this may have caused and thank you for using Lay Theme
Sincerely
Richard
