2. Type the command /rsp owntooltip
3.

What is the expected output? What do you see instead?

I expected to see my own tooltip window pop up for viewing my own info as it would appear to others. I received an error instead with no window.

Please provide any additional information below.

I'm using RantToolTip as my tool-tip modifier. Tool-tip settings in RSP are set to light. Will try other settings. Also suspect Prat as a problem due to chat frame errors shown, will disable it and retry.

I admittedly use a ton of add-ons. So far, most seem to play well with everything else.
