 * Hi there,
 * I am a big fan of AO so I installed it on my WP-MU installation.
    The problem
   is: Once activated I can not reach any of my wp-admin sites besides the main 
   one. They run properly for the public but every time I try to reach the specific
   admin panel of my sub-installations I get an error which states that there are
   too many redirects.
 * Please help me out, I really want to improve on my loadingspeeds.
 * – Jona

 * No idea what is happening I’m afraid Jona; my dev-machine has a multisite setup
   as well and I can access each site’s settings. probably a conflict with another
   plugin or with a code snippet (I vaguely remember one of the “solutions” for 
   automatic AO cache caused redirects, maybe that’s happening here)?

 * Thank you for the quick answer. I found out that it conflicts with my absolutely
   necessary domain mapping plugin. Do you use any domain mapping plugin or do you
   have any idea how I can solve this?
 * Edit: This is exactly my case: [https://wordpress.org/support/topic/redirection-loop-with-2-4-1/](https://wordpress.org/support/topic/redirection-loop-with-2-4-1/)

 * in that case can you apply the workaround described in [https://wordpress.org/support/topic/redirection-loop-with-2-4-1/page/2/#post-11192746](https://wordpress.org/support/topic/redirection-loop-with-2-4-1/page/2/#post-11192746)?

 * Great! I added this line to my wp-config:
    `define( 'AUTOPTIMIZE_SETUP_INITHOOK','
   init' );` Thank you for this amazingly fast support!
