upload_max_filesize alleine reicht nicht
Wer ‘upload_max_filesize’ in der ‘php.ini’ ändert, sollte auch ‘post_max_size’ anpassen, denn wie das PHP Manual erklärt:
‘post_max_size’ sets max size of post data allowed. This setting also affects file upload. To upload large files, this value must be larger than ‘upload_max_filesize.’
