Hi Martin,
That’s strange.
Could you please update the Stock Manager for WooCommerce plugin to the latest version if you haven’t already and then have a check. Let us know if it works after that.
If the issue still persists, then we’ll need to isolate what’s really causing this problem. Here’s something that will help:
- Install a free theme like Twenty Twenty or Storefront but do not activate/switch your current theme
- Install the free plugin Health Check & Troubleshooting
on your site – this plugin is developed by the www.ads-software.com team and is pretty good at diagnosing problems in such situations.
- Once the health check plugin is installed, keep only WooCommerce and Stock Manager for WooCommerce plugins active for the admin side and try to reproduce the issue you reported. Make sure to do this only for the admin side – that way visitors to your site won’t be affected.
- Here’s a nice article that explains this process.
- If the issue does not occur, it means the problem is with some other plugin. You may try activating/deactivating a combination of plugins to figure out exactly what causes the problem.
Alternatively, would suggest you to have a check with our best store management plugin – Smart Manager Pro using which you would be able to export stock for all variations and products. Also, you can manage your store more efficiently.
