We experienced a serious issue in one of our Moodle platforms. Flash animations that worked before, suddenly did not appear anymore. Instead, a warning message appears stating that the Flash player used is too old.
This issue was caused by a recent upgrade to the platform. For security reasons, a new parameter was added, that forces the Moodle users to upgrade to a specific version of the Flash player.
The default in my Moodle version (1.9.7) was set to version 10.0.12, which is pretty recent. In corporate networks, users often do not have the rights to upgrade the player, so this might cause some problems.
You can set the value to an earlier version, or leave the option blank to disable the checking. The option is called Required Flash Player Version and can be found in Site Administration – Security – HTTP Security.
nice tip… it just helped me.. thanks!
