UPDATE: I thought about this some more and logged back in as this member. I went into his preferences and changed the display date format setting. He had it as "day/month/year Time" so I changed it to "month/day/year Time" and went back to the forums, this corrected the display issue but on my computer. I am waiting for him to log back in and report.
I also changed my date display to where he had his but it did not cause the error. After I hear back from him I will ask him to change it back and see if the error repeats.
