Thread:Extension talk:PdfHandler/Thumbnail is not created

Hello!

I have mediawiki 1.24 installed an Windows 2008 Server (64bit) and I try to use PdfHandler. I updated from 1.19 to 1.22 to 1.24. In Version 1.19 PdfHandler worked but now on my actual version the Thumbnails are not created and the pdf is displayed as any other file.

I have the following settings: for PdfHandler:

for ImageMagick:

Former uploaded pdfs are displayed correct only from new uploaded ones the thumbnails are missing. Does anyone has an idea what is wrong or an idea how I can find out how to fix this problem?

Thank you in advance

Michael
