Thanks for being our customer. Please, make sure you are using the last version of the plugin and if that issue also visible when the default WooCommerce theme is enabled. Any other additional plugins are installed? perhaps there is a conflict between them. Check, please.
hello, I have disabled all the plugins and I have changed the theme and I see that the problem comes from the xstore theme because it works perfectly with the storefront theme, it may not be compatible with the subscritio plugin.
I also assume that the months and years once selected are displayed in white in the stripe payment form, which may be why you can’t see the characters. Can you correct this? Please thank you.
