I just upgraded to 1.20.2 and it seems to work fine. I downloaded SemanticMediaWiki and SemanticBundle into extensions. When I try to start up I get these errors. apache2 gets here through a symlink wiki ->wiki-1.20.2. Have I messed up a path someplace? *Warning*: include_once(/opt/local/apache2/htdocs/wiki-1.20.2/extensions/SemanticMediaWiki/SemanticMediaWiki.php) [function.include-once<http://localhost/wiki/index.php/function.include-once>]: failed to open stream: Permission denied in * /opt/local/apache2/htdocs/wiki-1.20.2/extensions/SemanticBundle/SemanticBundleSettings.php * on line *23* *Warning*: include_once() [function.include<http://localhost/wiki/index.php/function.include>]: Failed opening '/opt/local/apache2/htdocs/wiki-1.20.2/extensions/SemanticMediaWiki/SemanticMediaWiki.php' for inclusion (include_path='.:') in* /opt/local/apache2/htdocs/wiki-1.20.2/extensions/SemanticBundle/SemanticBundleSettings.php * on line *23* *Fatal error*: Call to undefined function enableSemantics() in * /opt/local/apache2/htdocs/wiki-1.20.2/extensions/SemanticBundle/SemanticBundleSettings.php * on line *24.* * * *LocalSettings has two other extensions, both working.
