I found the conflict, it was:
Cyb Tic-Tac-Toe.
I have no clue why this would cause a problem honestly but when disabled vbISpy works as expected.
My solution was to modify the main Tic Tac Toe "GS" plugin and edit the code, replace the first line (the if statement) with this:
PHP Code:
if ($vbulletin->options['cybttt_enable'] AND THIS_SCRIPT != 'vaispy')
Now it's working for registered users. :up: Thank you viper!
