Hi @davidstrejc ´
Thank you very much for your post.
Sorry to hear you have error coming up in your site. However, to find out what is causing it we need to dig a little deeper.
1. Does the error disappear when you get one version back with ATUM?
2. What is the version of WooCommerce and WP you on, pls?
3. Would you tell me the content of your PHP error log, pls?
Thank you,
Pavel
In PHP error log there is nothing related to this issue.
I am using ShopKeeper Theme and I did not try to switch to default.
I had to switch back to 1.5.8.8 and everything is working correctly.
I got WooCommerce 3.6.4
Anything else I can do?
Hi D,
I assume it is caused by another plugin?
Update your staging site to the latest and try disabling all plugins apart of 2 – ATUM and WC. Change your theme to any default WP.
Test if the error is gone. If it is, then I am correct and you will need to bring all back one by one starting with your theme. When the error shows, the issue will be the last activated plugin.
