Among other issues, I can no longer view Products > Products since 3.0 update. I can view Products > Add product, Products > Tags, etc just fine.

Database update was run and showed a message of success. I am asking how to re-run this in another thread but here is fine too.

WC Status page shows everything as green.

Enable WP_DEBUG – see whats output on that page instead of the error code. Or check server error logs.

Enabled debug. Nothing is shown (ERR_EMPTY_RESPONSE in Chrome).

WP log in wp-content contains only notices.

Apache log has a large number of notices, but I can’t tell if they are related.

[Tue Apr 04 14:57:26.916516 2017] [core:notice] [pid 1182] AH00051: child pid 6510 exit signal Segmentation fault (11), possible coredump in /etc/apache2

I have tried disabling plugins, etc.

What host is this? You could try them – 520 is a catch all error when something on the server goes wrong. Without a PHP error message relating to our code I cannot confirm if this is an actual bug or not.

I’m running on DigitalOcean. Everything has been fine for months. It definitely has to do with the update.

Can I just overwrite the plugin files in directory to rollback or will it clash with new database or something?

You can do that but it would be good to find out whats causing the breakage first or you’ll be stuck.

Ok, i’m really trying to narrow things down.

I can’t visit products pages, but I realized that I can look at stock notices. I know I have items that are out of stock. When I go to the page, it doesn’t display any items and there is an error:

Fatal error: Call to a member function get_sku() on boolean in /var/www/html/wp-content/plugins/woocommerce/includes/admin/reports/class-wc-report-stock.php on line 86

There’s also a notice on my product page.

Notice: WC_Product::get_upsells is deprecated since version 3.0! Use WC_Product::get_upsell_ids instead. in /var/www/html/wp-includes/functions.php on line 3829

Another notice on “Category view”:

Notice: id was called incorrectly. Product properties should not be accessed directly. Please see Debugging in WordPress for more information. (This message was added in version 3.0.) in /var/www/html/wp-includes/functions.php on line 4137

You said you had disabled other plugins? If you can see:

> Notice: WC_Product::get_upsells is deprecated since version 3.0! Use WC_Product::get_upsell_ids instead. in /var/www/html/wp-includes/functions.php on line 3829

That would be from something you have installed?

The notice, I don’t know. Will keep looking.

What about the fatal error?

That I can see would happen if the product it’s trying to get returned false instead of a product object.

I’m not sure if thats related to a plugin however.

Narrowed it down. My problem was the Abandoned Cart Lite by Tyche Softwares.

Faced other issues and had to disable WooCommerce Mix and Match by WooThemes as well.
