modx->sendforward displays blank page revo 2.2.2

I have a test document, with a snippet. the snippet contains the sendforward to homepage.


however, when I view this document, it just displays the blank page.
If i comment out the sendforward the document displays fine.

What could be the cause of this behaviour

The only thing different in my setup is the fact every page belongs to a "default" resource group, viewable by anonym - some other pages had to be authentication protected.

Is the sendForward() moving across Contexts? If so, go to System Settings, find the key "allow_forward_across_contexts" and set it to "Yes".

nope, I have this flag already set as this is the ultimate goal, however forwarding was just being tested and its all in the same context.

I can see that most of the times, people use the sendforward in plugins, rather than snippets on pages. Does this have anything to do with it?
Error log is blank too...

I cannot reproduce this problem; using sendForward() in a Snippet is working as expected in my tests. Can you provide more information?

how bizzare...
i just created a brand new page, included the same snippet and it all works as it should.
The old page still displays blank.
investigating...

well, after playing with page options on the problem page, cacheable/uncacheable
and a few other fields, i've changed the alias, saved and hit view - its forwarding correctly now as well.
im at a loss as to why. No other configs were changed.
The only other thing i can think of is my custom plugins, or supercache plugin messing with the cache...
