I have migrated a MW site onto a new VPS and noticed the version was old (1.16.1). So I updated it to 1.23.3 and after the upgrade, the thumbnails stopped working. Each thumbnail is now replaced by the message "Error creating thumbnail: File missing"
The thumbnails worked perfectly before the upgrade.
I switched on all the debugging by adding the following lines to LocalSettings.php:
# Debug mode on $wgShowExceptionDetails = true; $wgDebugToolbar = true; $wgShowDebug = true; $wgDevelopmentWarnings = true;
Nothing particularly useful is shown in the debug information that helps me identify the cause.
Today I decided to roll in the latest minor releases one by one and here are my results:
- 1.16.1 - 1.17.5 = OK
- 1.17.5 - 1.18.6 = OK
- 1.18.6 - 1.19.18 = BANG!
I looked at the release notes for 1.19 and also found some posts that I thought might be related to thumbnails and MW 1.19 but none of the solutions offered seem to help me at all.
- Imagemagick version: 6.7.7.10
- php5-imagick is installed
- php version: 5.4.4-14+deb7u14 (apache2handler)
- MySQL version: 5.5.38-0+wheezy1
It's beaten me... Anyone have any ideas? I'm hoping for something simple!
