Hi there,
I have MW 1.24.1 installed on CentOs7 with nGinx and PHP-FPM 5.4.16. I am not using ImageMagick.
With that stated, I am having an issue where thumbs are not being created for files when they are used in articles with a specific width defined. Image uploads work fine, and a thumb gets made when a file is uploaded (I assume it's what is displayed on the File:) page. However, attempting to use the image with a new size ends up with a 404 due to the thumb not being there. I am not getting any PHP errors, there is nothing in my system log or my web server logs that would indicate a permission issue.
I enabled debugging on a page that attempted to use a resized image, and the log can be found at http://pastebin.com/yeif2YHw
I don't know enough PHP to understand what the TransformationalImageHandler is doing, but I have a strong feeling that...
TransformationalImageHandler::doTransform: creating 150x200 thumbnail at mwstore://shared-backend/shared-thumb/6/67/BFZLogo.png/150px-BFZLogo.png using scaler gd TransformationalImageHandler::doTransform: Transforming later per flags. File::transform transformation deferred. (this appears for 3 different thumbnail sizes)
...isn't a good thing. The specific page that I am using to test this on (and which generated the above debug output) is http://wiki.magicjudges.org/en/w/User:Mumbles
I appreciate in advance any assistance you can give, and will provide whatever information I am able to if there's something that would help diagnose this issue.
Cheers, Adam
