Thread:Project:Support desk/Easy way to upgrade from version 1.8 to 1.22? - Part 2/reply (3)

Correct. When an extension is not included or required in LocalSettings.php, it will not be used and its functions will not be available.

So the stuff, which is no longer rendered is this:

According to this should be handled by Extension:DynamicPageList_(third-party). Update this extension from Git (using the newest version from the master branch; a branch for 1.22 does not seem to exist) and put these files in your installation instead of the old ones!

Next edit LocalSettings.php and activate the extension (again)!

Maybe you have to play with the syntax in these three lines inside the wiki page afterwards; I don't know that. See the section "Extended DPL functionality" at Extension:DynamicPageList_(third-party)!
