And getting some spurious error after searching for Psylocybe and going to his home page here...
There was a problem, now fixed, when clicking on an author name to display details. However, I didn't get the "home page" problem. Can you please describe the issue ?
Whatever the issue was it is now fixed.
It would show a line of text (some error) above the authors heading when you clicked the link to see the author home page. I assume where the Authors name was above the information box, handle, real-name etc..
