Not able to install on a new instance of Foswiki 1.1.3

I have installed and activated the extension, but it is not working for me. If i try to edit a chapter i only get a textarea with chapter text inside and "OK" and "Cancel" buttons as plain text. These are log entries i get, when the extension is enabled and any topic is loaded (not even edited):

-- MichaelPolivanov - 01 Feb 2012

Please upgrade to the latest EditChapterPlugin.Release: 4.31 - Version: 14611 (2012-04-16).It has been tested with a "vanilla"1.1.5 and 1.1.4 installation.The dependencies for this extension have been updated.

NOTE: This is tested with 1.1.3, but it requires a new version of JQueryPlugin which is incompatible with 1.1.3 configure unless patched - instructions in the "Compatibility" information in JQueryPlugin.
