Site acquisition issues - collective.siteisolation not working

Hi,

We are having issues at our university with plone sites being able to be acquisitioned from other plone sites. The sites having issues are plone 4.3.7, all on the same Zope and all the sites are on the root folder (no sites sub folders).

I've installed https://github.com/collective/collective.siteisolation which is suppose to solve the issue but is not working. It is setup in my buildout properly, successful buildout, I can see it installed and I restarted the clients. However, it is not solving the problem.

This is causing all sorts of problems for us. Is there another addon to fix this, or another patch?

Thanks,
David

There are 2 other approaches: https://pypi.org/project/collective.explicitacquisition/ and https://pypi.org/project/experimental.noacquisition/
I would test them if one of it serve your needs.
