With various DokuWiki installations (XAMPP on Windows, Std Ubuntu 14.04 Apache, Bitnami DokuWiki VM) I found the media upload limits completely effectless.
Regardless of my setting for upload_max_filesize and post_max_size in php.ini, I can upload files of much larger size (e.g. 70MB) through media manager - media manager in fact shows my set limit (e.g. "Upload max. 2 MB per file.")
Any hints on what to look at and/or change to get this fixed?
