 * My webhost is shared and the main website is set in the root directory. Five 
   other websites are located as subdomains (see structure below):
 * The P3 plugin worked with subdomains but caused an 500 server error in the main
   domain:
 *     ```
       /public_html/
       /public_html/wp code of main domain
       /public_html/wp-admin/ - maindomain wp code
       /public_html/wp-content/ - maindomain wp code
       /public_html/wp-content/plugins/ - maindomain wp code
       /public_html/wp-content/themes/ - maindomain wp code
       /public_html/wp-includes/ - maindomain wp code
       /public_html/subdomain_name/ - subdomain wp code
       /public_html/subdomain_name/wp_admin/ - subdomain wp code
       /public_html/subdomain_name/wp_content/ - subdomain wp code
       /public_html/subdomain_name/wp_admin/plugins/ - subdomain wp code
       /public_html/subdomain_name/wp_admin/themes/ - subdomain wp code
       /public_html/subdomain_name/wp_includes/ - subdomain wp code
       etc
       ```

 * Are you getting a 500 error on activation, or on use?

 * As I recall it accepts activation but I didn’t run it immediately because I wanted
   to install it on other (sub)domains.
 * When I went back to the main domain to run it crashed when I tried to get admin
   access. I contacted my webhost about the server 500 error and they identifed 
   P3 as the culprit and disabled it by moving it to another folder.

 * Hi Will,
 * Do you have the specific error they found? If so, I’d like to investigate this
   more thoroughly. For right now, I’m taking an educated guess …
 * I’ve seen this happen most commonly when a site was running very close to its
   memory limit. When you activate P3, it pushed it just over the limit and this
   error happened.
 * Removing P3 should fix the error right now. For the long term, consider raising
   the memory limit. You can confirm this is the case by looking for errors related
   to “memory limit” in your error logs.
 * To remove P3, remove the following files and folders via FTP:
 * wp-content/plugins/p3-profiler (the whole folder)
    wp-content/mu-plugins/p3-profiler.
   php (if it exists)
