Thread:Project:Support desk/Updating from 1.17 not working/reply (2)

Thanks! I turned on the error reporting and I am now getting the following output. There is indeed no "ScopedCallback.php" in "includes/libs". I should note that I just downloaded and extracted a fresh copy of the version 1.24.1 tar archive. Did I make some mistake in that process?

'''Warning: require(/home/linguist/public_html/wiki//includes/libs/ScopedCallback.php) [function.require]: failed to open stream: No such file or directory in /home/linguist/public_html/wikixx/includes/AutoLoader.php on line 1282
