Topic on Project:Support desk

Hi.

I freshly installed MW 1.24.0 on a dedicated server, and while everything else works,
"Fatal exception of type MWException" error pops up when I try to upload a file.

I have tried giving writable permission to the images folder, and tried almost every solution posted on this board,
and still haven't succeeded.

I'm running a CentOS 6, with PHP 5.3.3 & MySQL 5.1.73. I'm in desperate need of any advice.

ANY help would be grateful.
Thank you.

Here's the backtrace log.

[8ae2b2fe] /wiki/index.php/Special:Upload Exception from line 1871 of /home/ast-wiki/www/wiki/includes/filerepo/file/LocalFile.php: Could not acquire lock for 'Delete_error.PNG.'

Try adding this to LocalSettings.php:

$wgFileBackends[] = array(
	'name'        => 'local-backend',
	'class'       => 'FSFileBackend',
	'lockManager' => 'nullLockManager',
	'containerPaths' => array(
		'local-public'  => "{$wgUploadDirectory}",
		'local-thumb'   => "{$wgUploadDirectory}/thumb",
		'local-deleted' => $wgDeletedDirectory,
		'local-temp'    => "{$wgUploadDirectory}/temp",
	),
	'fileMode'    => 0644,
);
 
$wgLocalFileRepo = array (
        'class'             => 'LocalRepo',
        'name'              => 'local',
		'directory'         => $wgUploadDirectory,
        'scriptDirUrl'      => $wgScriptPath,
        'scriptExtension'   => $wgScriptExtension,
        'url'               => $wgUploadBaseUrl ? $wgUploadBaseUrl . $wgUploadPath : $wgUploadPath,
        'hashLevels'        => $wgHashedUploadDirectory ? 2 : 0,
        'thumbScriptUrl'    => $wgThumbnailScriptPath,
        'transformVia404'   => !$wgGenerateThumbnailOnParse,
		'deletedDir'        => $wgDeletedDirectory,
		'deletedHashLevels' => 3,
        'backend'           => 'local-backend',
);

Please come back to say if that works for you

I have this problem too. I'm using a hosting service.

No, it say another truble: Could not create «mwstore://local-backend/local-public/0/06».

That block of code fixed it for me. THANKS! I'm hosting on a windows 2012 Virtual Server with IIS8

Worked for me, too. Server 2008R2 with IIS 7.5
