I just updated an "older" Craft site (version 2.4.2702) to the newest update (version 2.6.2958).
But now all my image thumbnails in the back-end are missing and if I upload any new assets, the thumbnail is not generated and I get a Internal Server Error 500 on the front-end as the URL it points to is still the cpresources/transforms/283?x=qFc4lFWR5 kind of URL.
The image thumbnail itself is also not generated anymore in the folder it is supposed to go in. I didn't change any folder permissions (only updated the new app folder ofcourse with the correct permissions). I'm able to upload assets so the permissions should be fine I guess.
I've had issues like this before, but those were resolved, so I don't know what is causing this issue again. Is there anything I forgot about this update that I needed to change? I needed to do a manual update.
The logs I get are these:
2017-01-17 10:13:26 Level info Category application Message [Forced] Finished task 14 (GeneratePendingTransforms). 2017-01-17 10:13:26 Level info Category application Message [Forced] Starting task GeneratePendingTransforms that has a total of 0 steps. UPDATE
I do get a PhP error:
[18-Jan-2017 14:04:07 UTC] PHP Fatal error: Call to undefined method Imagine\Imagick\Imagick::getImageAlphaChannel() in MY-BASE-PATH-HERE/craft/app/vendor/pixelandtonic/imagine/lib/Imagine/Imagick/Imagick.php on line 191 But through the PhPInfo in the Craft CP I can see that Imagick extension 2.2.2 is installed with ImageMagick 6.7.2-7, so according to this page the method should exist: http://php.net/manual/en/imagick.getimagealphachannel.php.
UPDATE 2
As I justdumbly clicked rebuild"rebuild all asset indexesindexes" on the live CP insteadsite (instead of my local CP by mistake and now all images on the livelocal development site are gone. So this just becamein the browser tab next to it aaargh) I quickly added 'imageDriver' => 'gd', to the config as a serious URGENT issueworkaround. :/
