Description jeremybuchmann 2007-01-26 22:59:31 UTC 
PNG images are prevented from being uploaded.  Other image formats work fine. 
The error message is:

Upload warning
The file is corrupt or has an incorrect extension. Please check the file and
upload again.


My $wgFileExtensions looks like:

$wgFileExtensions = array('jpg','png','jpeg','gif','ogg','doc','xls','ppt','mp3'
,'odt','ods','pdf');


The problem seems to stem from the following line in the verify() function in
includes/SpecialUpload.php:

$mime= $magic->guessMimeType($tmpfile,false);

$mime comes back as "text/plain" which doesn't match the extension "png".

I should add that this is on Fedora Core 6.
Comment 2 Daniel Kinzler 2007-01-26 23:03:39 UTC 
Please read the FAQ before filing bug reports - see
http://www.mediawiki.org/wiki/FAQ#.22File_is_corrupt_or_has_an_invalid_extension.22

The cause is mostly likely a misconfigured php module.
