Hello Johanna

That client secret looks too short to me based on amelia2.png (from Stripe). They should look like this:

So, generally, they should be about the same length (they don't have to be necessarily). If you can provide me a temporary wp-admin user, I can log in and try with our credentials which I know work.

Please provide me a temporary WP-admin login for your site where this happens, so we could log in and take a look ‘from the inside’ as that’s the most efficient way to see and resolve the 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 party. 

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

Glad to hear that, Johanna

If you have any further questions or issues, please feel free to open a new ticket, and we'll gladly help.

Hello rca water polo

I responded to your ticket here: https://tmsplugins.ticksy.com/ticket/2555432/

So you can check my response there, and let's continue working on that ticket. Johanna's issue was something totally unrelated to the payment settings.
