I know that others have posted about difficulties with ImageMagick, but after reading in the forums here I'm still in the dark about the reason for the error I'm getting and what I should do about it. I'm running Omeka 2.3. I'm unable to upload any files at all. Here's the error message I get every time I try:
Omeka has encountered an error
Omeka_File_Derivative_Exception
ImageMagick is not properly configured: invalid directory given for the ImageMagick command!
exception 'Omeka_File_Derivative_Exception' with message 'ImageMagick is not properly configured: invalid directory given for the ImageMagick command!' in /var/www/vhosts/sunygeneseoenglish.org/walterharding.org/application/libraries/Omeka/File/Derivative/Strategy/ExternalImageMagick.php:83
