Question

I installed YetAnotherXpTrackerPlugin and all necessary plugins and perl modules. If I want to create a team, the following error appears:

Browser message 

TWiki detected an internal error - please check your TWiki logs and webserver logs for more information.
Can't locate object method "invalidate" via package "TWiki::Plugins::XpTrackerPlugin::WebDB"

I guess the following lines in /lib/TWiki/Plugins/XpTrackerPlugin/Functions.pm are producing the error: 

sub xpCacheInvalidate {
    # Force reconstruction of cache

    my ($web, $topic) = @_;

    # Invalidate the cache
    use TWiki::Plugins::XpTrackerPlugin::WebDB;
invalidate TWiki::Plugins::XpTrackerPlugin::WebDB($web, $topic); 

    $cacheInitialized = 0;
}

The plugin YetAnotherDBCacheContrib#invalidate_web_topic has a method called invalidate($web, $topic), but I haven't found the definition in one of the provided files.

So who can help me to fix this? smile

ALERT! If you answer a question - or have a question you asked answered by someone - please remember to edit the page and set the status to answered. The status is in a drop-down list below the edit box.

After some reinstalls, especially of YetAnotherDBCacheContrib the problem is gone...
