Hi there,

503 Errors can be caused by a variety of different things — there’s a guide to troubleshooting them here:
https://www.wpbeginner.com/wp-tutorials/how-to-fix-503-service-unavailable-error-in-wordpress/

As described in the guide, as a first step, I’d recommend deactivating all plugins aside from WooCommerce, and switching back to the default Storefront theme.

After that, try updating the WooCommerce plugin. If everything looks good, then switch the theme back and re-activate plugins one by one. If you see the issue return, then you know the last one activated is conflicting.

To avoid affecting your customers, you may want to try this on a test/staging site. If you don’t have one already, your hosting company might offer one as part of your package. Alternatively, you can use a free plugin like https://www.ads-software.com/plugins/wp-staging/

@kellymetal everyone who upgraded to the latest update is experiencing 503 errors. Even with default themes and NO other plugins. Clean server setup too. Please release fix ASAP.

Hi @mathewborja

Since yours may be a separate issue, could you open a new topic here with your system status? You can find it via WooCommerce > Status. Select “Get system report” and then “Copy for support”.? Once you’ve done that, paste it on the new thread.

Hi!
I want to inform that the plugin caused the error 503 Service Unavailable was Stock Manager for WooCommerce.
I deactivated plugin and my site worked again.
After, I activivated again Stock Manager, and it seems all works fine.

Best regards.

Hi @majograu ,

I’m glad you figured this out. Thank you for sharing your solution which might benefit other users.
