FULLCALENDAR does not render/show anything


I recently installed the FULLCALENDAR plugin and have the proble that it does not render anything. The page includes a call to


If I visit the page, there is just whitespace. So at least it looks like the macro is recognized.

I installed the plugin using the configure page. The plugins FullCalendarPlugin, ObjectPlugin, HijaxPlugin, FlexWebListPlugin and JQueryPlugin are installed and enabled. I installed the missing perl modules Date::Calc, JSON, JSON::XS, Time::ParseDate and double checked that they are displayed in "perldoc perllocal".

I first tried the plugin with Foswiki 1.1.6 and it did not work. So I upgraded to 1.1.8 to exclude any bugs, no difference.

There are no entires added to "working/logs/error.log" if I visit the page. Before a dependency was missing and there were entries added. Now it seems to be clean.

As I understood from the plugin description it is enough to install everything and call FullCalendar without parameters to show up a simple calendar.

Is there anything I forgot or overread?

I started a deeper examination of the problem by debugging it with firebug. Firebug reported an missing function in hijax.js: "foswiki.HijaxPluginConfigurableInit is not a function" in line 746.

I had no idea what to do about that so I just tried to re-install the HijaxPlugin. The re-installation was successfull and after going to the page with the call to FullCalendar again I finally saw the calendar. An error message poped up saying "ATTENTION: INSTANTIATE".

I found that the "INSTANTIATE" problem was posted before and fixed it following the instructions under

The initial problem seemed to be caused by the initial installation of the plugin. The automatic installation of the dependencies HijaxPlugin, ObjectPlugin and FlexWebListPlugin looks to be not 100% OK. These plugins showed an empty link under InstalledPlugins. After re-install the link of the plugins did point to existing topics. For completion I have to mention that before re-installation of the plugins I again found a premature END statement in LocalSite.cfg.

The end of the file was showing these lines:


$Foswiki::cfg{ForceDefaultUrlHost} = 0; $Foswiki::cfg{Register}{ExpireAfter} = 21600; $Foswiki::cfg{Plugins}{PatchFoswikiContribPlugin}{Module} = 'Foswiki::Plugins::PatchFoswikiContribPlugin'; 1;

Before re-installation I moved the __END__ statement at the end of the file. But now the file again looks like above. But the re-installation was succesfull and the calendar works. So the __END__ statement does not seem to be part of this problem.
