Installing PHx

I'm trying to install PHx on a localhost site, but I'm confused by the installation instruction:

4: Create a new plugin in the manager called "PHx" and copy/paste the contents of phx.plugin.txt into the code field.


How and where do I do this? According to one site I came across, I should...

"Click on the Manage Resources menu item in the Resources menu"


...but this doesn't exist!

Which version of MODX? If it's Revolution, which your other recent post refers to, you have no need to install PHx, since you have built-in input and output filters (see http://rtfm.modx.com/display/revolution20/Input+and+Output+Filters+%28Output+Modifiers%29)
;) KP

Aha, thank you.
Then I've a strange thing going on with MIGX placeholders not accepting output filters.

Thanks for the heads up.
