symlink issues

Concept:
I have 50+ wordpress sites on my server, all different client sites. I am tired of having 50 copies of most plugins and themes.
So my idea was to put all my plugins and themes into a special folder on my server and use symlinks for the sites to all access the same plugin and theme folders.


What I did:
I created a directory on my server /home/shawn/wordpress/wp-content/plugins to store my wordpress plugins in for all of my wordpress sites

That folder is for user & group shawn

I have a website bargainwp.com which has its own folder /home/bargainwp/public_html/wp-content/

I did a symlink:
ln -s /home/shawn/wordperss/wp-content/plugins /home/bargainwp/public_html/wp-content/plugins/

I added user bargainwp to the group shawn: (I want bargainwp to be able to update the plugin in admin)
usermod bargainwp -G bargainwp,shawn


Problem: I get a bunch of the following type of errors:
NetworkError: 500 Internal Server Error - http://shop.bargainwp.com/wp-content/plugins/home/shawn/wordpress/wp-content/plugins/woocommerce-subscriptions/css/admin.css

notice the path shows my /shawn/wordpress/.... instead of just /plugins/

Here is the line calling admin.css
wp_enqueue_style( 'woocommerce_admin_styles', $woocommerce->plugin_url() . '/assets/css/admin.css', array(), WC_Subscriptions::$version );

**Error logs show**
 Request exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace., referer: http://shop.bargainwp.com/wp-admin/admin.php?page=home/shawn/wordpress/wp-content/plugins/wp-traffic-tools/wp-traffic-tools.php


I have also noticed that when I try to configure many plugins, that I get the error: (You do not have sufficient permissions to access this page.)
example link with that error: http://shop.bargainwp.com/wp-admin/admin.php?page=wp-traffic-tools/wp-traffic-tools.php

I do NOT get that error when going to the same link with no symlinks under normal conditions.



Question:
I guess that my overall problem is the path showing /shawn/wordpress/.... how do I fix that part so it just shows the /plugins/ path?
