PHP Warning: Illegal string offset #95
Description
In the error-log of my apache-server, the following line appears often:
PHP Warning: Illegal string offset '_elem' in /var/www/html/wiki/lib/plugins/publish/action/revisions.php on line 37
It must have to do with arrays, but I don't know what to do exactly.
EDIT: it seems that this issue was investigated yet at #35
