Critical Error with thumbnail.php

[jannott]

Hello,
I have an issue with one of my websites. After updating laytheme and all plugins to the most recent version a page that before worked perfectly fine is completely unaccessible and shows a critical error. I used only two thumbnails on it and they seem to be responsible for the error since after activating wp-debug the debug.log shows the following errors.

Dear Jannik

@jannott

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.

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.

e it is not functioning.

---

If the above is confirmed and you still experience issue:

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

Armin can then have a better look 🔍✅

Best wishes Jannik & talk soon, have a wonderful day 🌝

Dear Richard,
checked everything, but there's still the same issue. I wrote an E-Mail a few days ago, but didn't get an answer yet – Since it causes a critical error it would be great if it could get solved asap.

Thanks
Jannik

Dear Jannik

@jannott

Could you please do a test with another Theme (wordpress default 2020 theme) and see if your Website still experiences this critical error? If so you will need to contact your Webhost.

I will once again forward to Armin to be sure ✅

Best wishes Jannik 🌻
