Hello, Please help me understand the following error I get when I add:

$wgProfiler['class'] = 'ProfilerXhprof'; $wgProfiler['output'] = [ 'ProfilerOutputText' ]; $wgProfiler['visible'] = true;

to my LocalSettings.php per [1] in order to enable "Profiling".

There error is:

"Fatal error: Uncaught Exception: Profiling is already enabled. in /opt/htdocs/mediawiki/includes/libs/Xhprof.php" and then it gives the stack trace [2].

When I disable the "class" line and such that the configuration is just:

$wgProfiler['output'] = [ 'ProfilerOutputText' ]; $wgProfiler['visible'] = true;

I get nothing added to my page to diagnose.

Any insights on this would be great. Thank you! /Rich
