 * I have been having an issue with my server load jumping from normal to 40s-50s
   when this plugin is enabled? I never had any issues before but now I am seeing
   this happen. I narrowed it down by activing all plugins but this one and server
   load was normal. After activating this plugin my server locks up and load jumps
   super high.
 * Is there something that could cause this?

 * The first thing I would check for is a rewrite rule that is causing a rewrite
   loop. Rewrite loops tend to send Apache off the deep end.

 * Would that make sense with why once I enabled the plugin I would almost immediately
   see the Google Analytics real time visitors number rise by a bunch?
 * Could you please point me in the right direction to look for the rewrite loop?
 * I really appreciate your help and quick response. Been searching for an answer
   and this seems to be on the right track.

 * No, a rewrite loop happens before any of the page is loaded where the GA scripts
   are).

 * Can you post your .htaccess and some info on your set up?

 * I currently have a multi-site install setup in my public_html directory. It uses
   sub-domains. I am using C-Panel on a Linux server with wildcard sub-domains setup.
 * Here is my .htaccess file
 *     ```
       #deny from all
   
       # BEGIN WordPress
       <IfModule mod_rewrite.c>
       RewriteEngine On
       RewriteBase /
       RewriteRule ^index\.php$ - [L]
       RewriteCond %{REQUEST_FILENAME} !-f
       RewriteCond %{REQUEST_FILENAME} !-d
       RewriteRule . /index.php [L]
       </IfModule>
       # END WordPress
   
       AddOutputFilterByType DEFLATE text/plain
       AddOutputFilterByType DEFLATE text/html
       AddOutputFilterByType DEFLATE text/xml
       AddOutputFilterByType DEFLATE text/css
       AddOutputFilterByType DEFLATE application/xml
       AddOutputFilterByType DEFLATE application/xhtml+xml
       AddOutputFilterByType DEFLATE application/rss+xml
       AddOutputFilterByType DEFLATE application/javascript
       AddOutputFilterByType DEFLATE application/x-javascript
       ```

 * You need to update your .htaccess to the one shown in Network Admin -> Network
   Setup.

 * Yes! Great catch.
 * I have re-activated the plugin and haven’t had any load issues since.
 * Thanks again for your help.
