Trouble buying a horse

[Showjumping Dreams]

Please help!

I tried to buy another player's horse but I get a warning message saying "the horse's field needs to be a numeric value, equal to, or higher than 0."

Does anyone now how to fix this or what it means?

Thank you.

This is a known bug.

Thank you for replying but I don't understand what to do. I clicked on the link but I don't know what to do afterwards.

I'm sorry, the horse cannot be sold at the moment.
