Error when trying to add a new service

Hello team,
I want to add a new service to the reservation system, and when I add rates, it takes me off the screen and says: error.

Please help.

Dear Javier,

Please, send a screenshot with an open console for us to investigate the error logs.

To open the dedicated ‘Console’ panel on Chrome either:

  1. Use the keyboard shortcuts. On Windows and Linux: Ctrl + Shift + J. On Mac: Cmd + Option + J.
  2. Select the Chrome Menu icon, menu → More Tools → JavaScript Console. Or if the Chrome Developer Tools are already open, press the ‘Console’ tab”

Looking forward to your reply.

Best regards,
​Anna
