Be careful with this plugin

I used it once a few days ago and it worked without problems. I started a scan again yesterday and after afew minutes the plugin threw an error:

Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 72 bytes) in /var/www/XXXXXXXXXXXX/wordpress/wp-content/plugins/p3-profiler/classes/class.p3-profiler.php on line 300

Since then I have not yet managed to re-login into the admin panel to stop it or uninstall it. I can’t even see my website any longer. It works for others (probably an IP issue).

It’s kind of risky to use it with news wordpress versions.
