Hi all,

first of all I hope I'm posting in the right section.

I suddenly have an issue with my dokuwiki, more precisely with the media manager and site map. When I try to upload an image via the media manager or even check the already uploaded files via the media manager I receive an HTTP 500 error.

Checking the error.log from apache I found the following line with regard to the error:

[Thu Oct 04 19:16:03.037298 2018] [:error] [pid 1178] [client 10.0.0.65:56828] PHP Fatal error:  Call to undefined method PostInput::filter() in /usr/share/dokuwiki/lib/exe/ajax.php on line 18, referer: https://raspberrypi.fritz.box/dokuwiki/doku.php?id=start:manuals&do=medi...

Looking at line 18 in the /usr/share/dokuwiki/lib/exe/ajax.php I found this:

$call = $INPUT->post->filter('utf8_stripspecials')->str('call');

Another thing I recognized is that I'm not able to expand the namespaces in the site map. I get the same error as mentioned above.

Do you guys have any ideas what could be the problem?

Thanks a lot in advance.

Mike
