Hi,
I have upgraded my site from the first version 6 to 07.02.01 and after to 07.04.01. The upgrade was successful, but now when I work in the site, the error "HTTP Error 503. The service is unavailable" appears very often; the IIs default apppool craches and I have this error in the event viewer of the server: "Impossible to find the assembly 'Lucene.Net, Version=3.0.3.0, Culture=neutral, PublicKeyToken=8508". Please can I have help in resolving this issue?
Best regards,
