Thread:Project:Support desk/Problems with Thumbails - Update from 1.9 to 1.1x

I have several internal LAMP Wiki Installations. One of them is the mediawiki Version 1.9. I have to update it to 1.1x. My last try is to Update to 1.10.4. The update was without Problems execpt: No Images! in 1.9 the Images are stored in wiki/images, after the Update he creates the thumbnail directories like wiki/images/thumb/5/5a/FILENAME.PNG/ but this directory is empty. On the wiki pages I have the errormessage --- Error creating thumbnail: convert: unable to open image `/var/www/mediawiki-1.10.4/images/5/5a/American_Threads.PNG': No such file or directory. convert: unable to open file `/var/www/mediawiki-1.10.4/images/5/5a/American_Threads.PNG'. convert: missing an image filename `/var/www/mediawiki-1.10.4/images/thumb/5/5a/American_Threads.PNG/800px-American_Threads.PNG'. --- the directory /var/www/mediawiki-1.10.4/images/5/5a/American_Threads.PNG not exist, but /var/www/mediawiki-1.10.4/images/thumbs/5/5a/American_Threads.PNG In the LocalSettings.php are the variables enabled $wgEnableUploads = true; $wgUploadPath = "$wgScriptPath/images"; $wgUseImageResize = true; $wgUseImageMagick = true; $wgImageMagickConvertCommand = "/usr/bin/convert"; $wgHashedUploadDirectory = true; have someone an Idea was is wrong? kind regards Manuel PS: www-data (apache user) and "others" has full rights (777)
