Don't see a way to contact the author directly; Daniel Werner I have installed it from the latest files and when I try to run update.php after installation, it craps out with several errors. I did not understand the following installation instructions; "This extension will require PHP 5.3 or higher. It also depends on a bugfix for bug 34678 which has to be deployed manually for the time-being." Which I got from the installation manual page. Can you tell me how this is done. The "bug fix" installation is way beyond my experience on these, but I NEED SemanticWiki to work properly. Thanks John
