Thread:Extension talk:Semantic MediaWiki/Update Semantic Mediawiki but cant run update.php

I used composer to update my semantic mediawiki version. The installation ran successfully but I cant update.php. My current SMW version in 1.8.05. Running update gives me an error that says SEMANTIC MEDIAWIKI MUST BE INSTALLED TO RUN SEMANTIC FORMS. I did try placing the enableSemantics call at the end of LocalSettings.php file. Please help. Thanks in advance
