How to change the color of the text

Hi, you can disable the styling of green and red messages using the op_use_frontend_styles filter, beyond that the plugin doesn’t provide styling so it would have to be done in the theme styles.

Please refer to the styling section in the FAQ

Hi, I use the website for my local store – I don’t know anything about code; which file do I have to change to disable the styling of red and green?
Besides that, I love your plugin ??
