I hope you are fine. (Nice weather for bbc, isn't it?)
1.)
there is a little bug in "class.content.inc.php" which should be corrected in all mle versions (e.g. CreateFrontendLink() don't work correct).
2.)
Well, I have done some additional tests. And there was really a problem with some module action and if internal pretty url is enabled. I have attached a new patch (which also respect the above "class.content.inc.php" patch).This is a patch that I wanted to test more thoroughly before you include it.
Regards,
Carsten
