I have taken new servers and configuring my sites.
When I activated wp super cache plugin I got permission warnings. I followed instructions provided till adding define('WP_CACHE', true); to config file.
After this step, am getting error 500 Server error.
Front end & wp-admin both are having same issue.
Same problem repeating in all my servers, unable to fix even following few instructions provided in web.
I really tired and posted for solution.
Please help.
Thank you.
