Dear all. I’m using Nextcloud 10.01 on Ubuntu 16.04LTS - and so far everything’s fine.
But on another setup I have following problem.
Ubuntu 14.04 PHP5 NC10.01 (fresh Setup of NC). So far so good, but it’s impossible to set a log in image via webinterface. I see no entry in nextcloud.log.
Does anyone has the right tipp??
Update: Here’s the apache error.log
[Wed Oct 05 01:55:09.747886 2016] [:error] [pid 1494] [client 220.127.116.11:50124] PHP Parse error: imagescale(): one parameter to a memory allocation multiplication is negative or zero, failing operation gracefully\n in /var/www/cloud/apps/theming/lib/Controller/ThemingController.php on line 211
There was a bug report in the past: https://bugs.php.net/bug.php?id=65171, not sure if the fix made it in ubuntu 14.04. If it fails at very large pictures, you can reduce the size of an image for which a thumbnail is created (workaround):
* max file size for generating image previews with imagegd (default behaviour)
* If the image is bigger, it'll try other preview generators,
* but will most likely show the default mimetype icon
* Value represents the maximum filesize in megabytes
* Default is 50
* Set to -1 for no limit
'preview_max_filesize_image' => 50,
