Hi,
I've noticed some strange behaviour in your plugin.
When the option "Individual fixed amount for coupon" for plugin WooCommerce Currency Switcher is on and the client added a coupon (percentage, 10) no special rules, unlimited usage.
Then the coupon works properly in cart for the base currency. As soon as the currency was switched from default to for example EUR then the coupon started to throw a fatal error in the cart.
Some stack trace:
PHP Fatal error: Uncaught WC_Data_Exception: Invalid discount amount in /var/www/html/web/wp-content/plugins/woocommerce/includes/abstracts/abstract-wc-data.php:856
Stack trace:
#0 /var/www/html/web/wp-content/plugins/woocommerce/includes/class-wc-coupon.php(528): WC_Data->error('coupon_invalid_...', 'Invalid discoun...')

#7 in /var/www/html/web/wp-content/plugins/woocommerce/includes/abstracts/abstract-wc-data.php on line 856
This leads to the culprit which is woocs_after_33.php #4600 woocommerce_coupon_loaded()
line 4619 if ($this->is_fixed_coupon) {} which is read from the options as far as I saw.
In the end when debugging it caused a confusion to woocommerce because the amount was translated from 10% to 150 -> and this throws an error as the percentage can't be more than 100.
I am not sure what this function is doing because it doesn't allow me to enter multiple currencies in the coupon edition menu in Woocommerce.
But fixing the fatal error is as easy as disabling it. Is this a bug? Or do I not understand the functionality?
