Parallel Use as Web Store and Donation Page

Some potential users may be confused by this warning:

Note: Donation Platform for WooCommerce: Fundraising & Donation Management turns WooCommerce into a donation system, parallel use as a normal store is not recommended, as some wording has been changed.

In fact, Donation Platform for WooCommerce does not change the core functionality of WooCommerce, so you can continue to sell products normally. However, the wording in the user frontend has been adjusted. For example, the order summary is now called “Your Donation” instead of “Your Order”, the title of the order history and the texts of the emails have also been adjusted accordingly.
If this is not a problem for you, you can continue to sell normal products. Otherwise, my recommendation would be that you use a WordPress multisite or a separate WordPress installation for the donation page. Or you can use the free Loco Translate plugin to customize the texts.
