Hey there!
Can you please provide more information to reproduce the issue? Here’s what I tried:
1. Create a Simple product
2. Set 15 regular price
3. Set 10 sale price with sale dates 2019-07-24 until 2019-07-31
4. Save the product
5. Enable inventory management and set stock 0
6. Save the product
7. Change sale dates
8. Save the product
I was able to change the sale date using these steps.
In addition, I suggest doing a conflict test to determine if the issue is coming from another plugin and/or the theme you’re currently using. The best way to determine this is to:
?
- Temporarily switch your theme to Storefront
- Disable all plugins except for WooCommerce
- Repeat the action that is causing the problem
If you’re not seeing the same problem after completing the conflict test, then you know the problem was with the plugins and/or theme you deactivated. To figure out which plugin is causing the problem, reactivate your other plugins one by one, testing after each, until you find the one causing conflict. You can find a more detailed explanation on how to do a conflict test here.
