 * Visually, the checkout looks very appealing with this plugin, but unfortunately
   it appears to break password validation, or modify the wrong hooks, and the user’s
   login details subsequently generate an error. My theme (Storefront) is supposed
   to be compatible, but doesn’t appear to be.

 * Hello Rogier,
   I have tested the Storefront theme, version 4.6.1, with the latest
   of Fluid Checkout and could not replicate any of the issues you mentioned.
 * It is likely that this error is a conflict between plugins, so it would be helpful
   if you could [**run a plugin conflict test**](https://docs.woocommerce.com/document/how-to-test-for-conflicts/)
   to find out which plugin or theme might be conflicting with Fluid Checkout.
 * Basically, you temporarily deactivate all plugins except for WooCommerce and 
   Fluid Checkout, then re-activate each plugin one by one until you find one that
   causes the issue. Ideally this should be done in a test/staging copy of your 
   website. You can find more specific instructions in the article below from WooCommerce:
   
   [https://docs.woocommerce.com/document/how-to-test-for-conflicts/](https://docs.woocommerce.com/document/how-to-test-for-conflicts/)
 * Once we know what plugin or theme is causing this compatibility issue with Fluid
   Checkout, then we can work on fixing it.
   Kind regards,Luiggi
