Trying to get better debugging reports from php. Modified the php.ini file in sarneil/www
error_reporting = E_ALL
display_errors = on

added some instructions to the .htaccess file

Also in the config.php.ini file, set display_errors to on.

Resulted in 505 internal server errors, so gradually removed things and eventually got the instance to reappear with no .htaccess file and the modifications to the php.ini and config.php.ini intact.

Still no success with creating a default plugin. The code snippet I took from the dataverse example caused a php error (presumably one of the calls is to a library it includes, but I haven't. The example from the documentation throws no errors, but does not write the link out that it is supposed to.
