Several frequently-seen status codes have “friendly” error messages
that Internet Explorer 5.x displays and that effectively mask the
actual text message that the server sends.
However, these “friendly” error messages are only displayed if the
response that is sent to the client is less than or equal to a
specified threshold.
For example, to see the exact text of an HTTP 500 response,
the content length must be greater than 512 bytes.

Hi again if I run it through terminal as sudo it works fine ???

Have you searched the forum - there have been several topics like these two where there been a lot of discussion - especially regarding SQLite & Mono version which needs to greater the 4.6.+
