I just installed StackSizeController and configured it to be used by the default group. 

When I run /stack, I get the error "Stack size controller has encountered an error while trying to read the data file. Please contact me.. yada yada yada"


It is in the right dir, I have other mods and they work.

I validated with Jsonlint, you can check it yourself.  Copy pasted from this file.https://pastebin.com/S6mNvCCX

Any ideas?

Edit, I thought of this, right as I posted it, and it fixed it.  I originally brought this file down into Notepad ++ to do some fancy replaces on it and by doing so somehow modified the file permissions.  If you do this, do not upload the file back to the server, but rather just paste the contents of it into the file on the server.

I fixed this by deleting the current StackSizeController.json and issuing an oxide.reload StackSizeController then modifying the newly created file. CP the contents of my local file et viola.

Hope this helps someone else.
