Thread:Extension talk:Renameuser/Missing function?

Hello everybody,

I've just updated my wiki from version 1.16.2 to version 1.23.5 and updated the extension Renamuser to the current version. But when I try to open the rename-user-page in my wiki I get the following error-message:

When looking at the file mentioned in the error-message I noticed that there is indeed no such function as getOutput in this file. With the help of grep I ensured that there is no such function in the whole /opt/lampp/htdocs/_fhbwiki/extensions/Renameuser-directory

I even went so far as to have grep look in my whole wiki-directory:

Here is the result of that grep:

Now I'm wondering whether one of those getOutput-functions is the one the Renameuser-extension is supposed to use and why that isn't working properly? The reason I wondering that at all is that a similar "Fatal error: Call to undefined method"-error-message occured when I tried to update another extension before. But since it turned out that the older/previous version was working fine I didn't follow up on the update and the error any further...

I'm a rather PHP-noob so I cannot really follow up all the programming-intricaies indepth. :-( I hope someone can help me or at least point me in the right direction.
