Hello all,
Sometimes I do a GET Request and get a 500 error (at the same time I
get 404 not found errors for other ldp containers with the browser
interface). Any ideas about troubleshooting? Thanks.
-----------------------------------------------------------------------------------------------------------------
The result of get is
string(8195) "HTTP/1.1 500 Internal Server Error
