First off, if FetishCentral is off screen for some reason, you should be able to open the locator with the following command (Caps matter).
Code:
/show_window Custom.Locator
If that doesn't work...
You either didn't update
eq2ui_custom.xml or, after updating it, you replaced it with one that wasn't updated.
eq2ui_custom.xml should contain the following includes...
Code:
<include>_Fetish_bagstrip.xml</include>
<Include>_Fetish_buffimmunity.xml</Include>
<Include>_Fetish_clickabilities.xml</Include>
<Include>_Fetish_clickcures.xml</Include>
<Include>_Fetish_fetishcentral.xml</Include>
<include>_fetish_infocenter.xml</include>
<include>_Fetish_inventory_dock.xml</include>
<include>_Fetish_locator.xml</include>
<include>_Fetish_personabar.xml</include>
<Include>_fetish_refresh.xml</Include>
<Include>_fetish_refreshfilters.xml</Include>
Likewise, similar includes need to be removed from
eq2ui_mainhud.xml and
eq2ui_inventory.xml. Leaving the old includes in those files could cause the UI to load 2 windows of the same name, which can confuse scripting.
If you're having problems and have not done a clean install of v11.1, you probably should try it. Rename you're old FetishNightfall directory, then follow the installation instructions.
