I am using Magnolia 4.4.4 Community Edition on Jetty.

When accessing the Magnolia store I get the following Exception :

FreeMarker template error!

Expression this.postdata is undefined on line 60, column 55 in info/magnolia/module/storeclient/pages/AllModulesListPage.html.
The problematic instruction:
----------
==> ${this.postdata} [on line 60, column 53 in info/magnolia/module/storeclient/pages/AllModulesListPage.html]
----------

Java backtrace for programmers:
----------
freemarker.core.InvalidReferenceException: Expression this.postdata is undefined on line 60, column 55 in info/magnolia/module/storeclient/pages/AllModulesListPage.html.
