php_flag allow_call_time_pass_reference: For some reason, which I haven't figured out yet, the wiki needs the php_flag allow_call_time_pass_reference to be turned on. So, in order to get it to work, set the php variable php_flag allow_call_time_pass_reference in your .htaccess file. This issue will be solved in a future version of DR Wiki.

Problems with realURL: There seem to be some problems with DR Wiki and the realURL extension. When using both of them, the wiki-links will be rendered wrong. I hope this issue will be solved, as soon as I have switched all links to typolinks.
