Strange, there should be a template called Icash_donate because I find this in the product xml file:

template name="ICash_Donate" templatetype="template.. etc.

Anyway, I'm sure in the Icash settings in the AdminCP is a yes/no option to NOT use the postbit changes. This should be set to no. Then the donate option is gone.
Don't forget to remove the donate.php from your forums directory.

If you really can't find it, I think you can delete this line from the product xml file, but this is not advisable, I would suggest not to use this method:
Find this line in the product-icash.xml:

		<plugin active="1" executionorder="5">
			<title>ICash Postbit Edit</title>

Change it to:

		<plugin active="0" executionorder="5">
			<title>ICash Postbit Edit</title>

After that, reimport the product file and don't forget to put "overwrite" to "yes".

Now all postbit editting is gone, also the display of the amound of cash a user has.
If you want that part back, use my suggestion from my previous reply, to use the documentation in the 1.1.2 zip on how to make a postbit(_legacy) edit manually.

Again I would not advise to change product-xml files, use at your own risk.
