Some early de-bugging steps before we move forwards if you are able:
Do you have any Third-party plugins installed that when de-activated resolve the issue, sometimes they cause clashes with the Theme?
As you mentioned your Lay Theme is up to date, however are any Addon's that you may have purchased also up to date?
Sometimes with Wordpress when it updates you need to simply go into "Settings - Permalinks" and just click "Save Changes" to refresh the sites permalinks, does this have any affect?
If none of the above work for you and you do believe it is a Bug we would love to know as we can then resolve it quickly for you as well as other users who have this issue,
could you please send your website address, /wp-admin/ username and password and a link to this topic to email@example.com?
And we will get back to you shortly,
In the meantime thank you for using Lay Theme and your patience with these issues,
