Hi there ??
This kind of problem is usually caused by a conflict with your theme or with another plugin. The best way to determine this is to:
- Temporarily switch your theme to Storefront
- Disable all plugins except for WooCommerce
- Check your product page
If you’re not seeing the same behavior after completing the conflict test, then you know the problem was with the plugins and/or theme you deactivated.
Reactivate the theme first and check again. Then, go on and 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: https://docs.woocommerce.com/document/how-to-test-for-conflicts/.
Once identified, you’ll want to reach out to the theme or plugin developer directly to report the issue.
Thanks.
