Fatal JS errors on Mobile on Lay 4.1.0

---

Since a recent Lay theme update our site https://dominikbachmann.com (user & pw: 0000) is no longer working on mobile (desktop works fine), due to fatal JS errors that occur both on load and on menu click:

ON LOAD error:

Dear @brogr

Please confirm 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 (most likely).

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.

Sorry to give a list @brogr but this will help narrow down the possible issues for the future.

Best wishes

Richard

Hi @Richard

Can confirm that we've tested all the conditions you listed. The error persists.

Best,
Brogr

Thanks for testing @brogr Have forwarded this to Armin for further inspection ✅ could you also:

Please send your website address, /wp-admin/ username and password and a link to this topic to info@laytheme.com?

Talk soon & have a wonderful day ✨

Richard

@Richard i have sent the information to info@laytheme.com

Thanks @dbachmann ⭐️

Hey @Richard, any news yet on the issue? Or might it be an option to downgrade to an older version? If so, could you provide us with a ZIP.

hey there seems to be an issue where this bug happens when you have activated the tag filter for a project thumbnailgrid but it doesnt contain any tags

i deactivated the tag filter for you

but of course this is a bug and i need to fix it!
