I was trying to look at stats for my computers and I found that clicking on the graph links for POEM@Home gave an Internal Server Error:

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, [no address given] and inform them of the time the error occurred, and anything you might have done that may have caused the error.

Apache/2.2.22 (Debian) Server at wuprop.boinc-af.org Port 80

bfgminer (Campaign #13) (for 20+GH/s Blade erupter ASICs)
I found that this error occurs for any app name that includes plus or pound symbols. For example, Gamma-ray pulsar search #4, bfgminer (Campaign #13) (for 20+GH/s Blade erupter ASICs), Gravitational Wave search S6Bucket Follow-up #2, POEM++ and POEM++ OpenCL version.

You can find all these on the page for Upload/Download http://wuprop.boinc-af.org/results/dl_ul.py but I find the same behavior on other pages
