Can't see the results of my herbalist

Hello,

I'm experiencing a bug that suddenly appeared when I want to see the results of my herbalist. A blank page appears with this message at the top : "An error has been logged - please reference #34802fd if making a bug report"

What am I supposed to do exactly ? Do I have to report this bug ? Or is it something that only appears to me ?

Thank you in advance for  your help,
