PRO v5 kills WooCommerce REST-API

Support
#1

Hi there, yesterday we found out, that the REST-API of a client’s ecommerce website was not working. They could GET (200) the orders successfull but when they tried to access the products, the WooCommerce REST-API always returned Error 500. We deactivated all of the plugins, downgraded WooCommerce, switched the SSL-Certificate and after two days we found out: It was PRO (v5)!

This is the Debug-Message we received when we tried to access “/wp-json/wc/v3/products/”:

Fatal error: Uncaught Exception: Unable to load content from post. in /var/www/vhosts/XXX.com/httpdocs/wp-content/themes/pro/cornerstone/includes/classes/content/class-content.php:58 Stack trace: #0 /var/www/vhosts/XXX.com/httpdocs/wp-content/themes/pro/cornerstone/includes/classes/content/class-content.php(28): Cornerstone_Content->load_from_post() #1 /var/www/vhosts/XXX.com/httpdocs/wp-content/themes/pro/cornerstone/includes/classes/element/class-element-front-end.php(208): Cornerstone_Content->__construct() #2 /var/www/vhosts/XXX.com/httpdocs/wp-content/themes/pro/cornerstone/includes/classes/element/class-element-front-end.php(87): Cornerstone_Element_Front_End->get_content() #3 /var/www/vhosts/XXX.com/httpdocs/wp-content/themes/pro/cornerstone/includes/classes/element/class-element-front-end.php(70): Cornerstone_Element_Front_End->render_the_content_cached() #4 /var/www/vhosts/XXX.com/httpdocs/wp-includes/shortcodes.php(356): Cornerstone_Element_Front_End->render_content() #5 [internal function]: do in /var/www/vhosts/XXX.com/httpdocs/wp-content/themes/pro/cornerstone/includes/classes/content/class-content.php on line 58

We downgraded to PRO 4.3.3 and finally everything was working again.

Could somebody tell me what the hell was going on there? I really did not think that a theme could interrupt a WooCommerce REST-API… Is this a bug or is there something wrong in our Server / System?

Looking forward to hearing from you soon.

Best regards from Germany

PS: Im a Themeco ELITE client but i wanted to share this error in public as i could not find anything about it on the internet so far.

Hello @partnerundsoehne,

Thanks for writing to us.

It might be the issue of the version compatibility issue. Please make sure your theme, plugin, WordPress Core, and PHP version are updated as per our version compatibility page.

It would be best if you could copying your live website to your staging area. and check it. In case if it doesn’t work for you I would suggest you troubleshoot with a few of the common issues before we investigate your settings.

  5. Css/Js Customization
  6. Increasing Php Memory Limit
  7. Disabling Cache
  8. Disabling Cdn
  9. Permalinks
  10. Version Compatibility

If none of these work for you please share your details in a secure note so that we can investigate your setting without breaking your live site. Please provide the following details
