Hello Hans, 

Could you please tell us have you maybe added custom currency in Amelia -> Settings -> Payments? Or you only had chosen Euro for the Currency option? Sorry for any inconveniences this have caused, our developers are working on finding where the issue is coming from, we couldn't reproduce the issue on our end, so could you please provide me a temporary WP-admin (administrator) user for your site where this happens, so we could log in and take a look and try to find out what could cause this issue?

We do not interfere with any data or anything else except for the plugin (in case that’s a production version of the site), and of course, we do not provide login data to third parties. 

You can write credentials here just check PRIVATE Reply so nobody can see them except us.

In order to try to fix it now on your website, please go to the Settings page in Amelia and in Payments just add the euro symbol to the 'Custom Currency Symbol' option, save the change and let us know if this fixed the issue. 

Hi Hans

Thank you for the update, we are glad to hear that

If there is anything else we can assist you with please don't hesitate to open a new ticket.

Have a wonderful day!
