Hi,
Sorry to go over this same issue again but I’ve had this same problem re: memcache etc.
I contacted my hosting provider and they replied as below:
“Please note that we run PHP as CGI/suPHP module when it runs in such mode, PHP scripts won’t be able to detect most of enabled Apache modules.
You can find more information on WordPress support site,
http://wordpress.org/support/topic/plugin-w3-total-cache-compatibility-test-errors?replies=7#post-1627402
Note that some of those modules(mod_deflate / mod_gzip, Opcode cache and Memcache) can’t be installed/enabled on our servers.
Other modules are enabled and you can disregard these warnings.”
As you can see they directed me to this page. I’m a little confused by their message and wondered what this all means. I’ve used firebug to check my speed and get a 83/100 rating yet pingdom and alexa are both telling me my site is slow.
I’m becoming more and more confused and would appreciate a little guidance. My website is http://www.becandolifecoaching.com
Thanks
Jacky
