Currently I use Bootstrap Default version 1.0.6 and I got a notification for a new version. However, upate does not work. I just get the popup message "an error occurred" but no further details.
Is there a way to get more details about the error and any solution to fix it?
Piwigo version: 2.8.6
PHP version: 7.1.2
