apps » new apps

i tried to add webcal using the "New Web App" function and hda setup page, which it added i found that i had done it incorrectly and tried to remove it by using the "Delete web app" button, when i selected it the webpage shutdown and i was unable to open of the webpages.
using webmin to check on a few things i found that Apache had shut down and would not restart until i had remove the Virtual server from the Apache webserver i then restarted Apache with no problem.
on reviewing the hda setup page i noticed that the webapp i tried to link is still there, i have not tried to see if it runs i case i get another failure
