[Plugin: W3 Total Cache] suPHP not compatible with either memcache or APC?

Unfortunately it is true ?? You can try FCGI as an option.

Really? My webhosts seems to be very good as they got memcache installed and working on VPS alongside suPHP.

I also did some search and found this that says it can be installed and get to work together.

But APC is still a no-no with suPHP.

Memcache has been installed and working on my VPS, but whenever I choose memcache as the caching method I get the following error messages:

Page caching is not working properly. Memcached server(s): 127.0.0.1:11211 may not running or not responding. This error message will automatically disappear once the issue is resolved.

Minify is not working properly. Memcached server(s): 127.0.0.1:11211 may not running or not responding. This error message will automatically disappear once the issue is resolved.

Object caching is not working properly. Memcached server(s): 127.0.0.1:11211 may not running or not responding. This error message will automatically disappear once the issue is successfully resolved.

Anyone else who had the same issue?

If you are seeking a solution for optimizing your website loading speed, try the combination of plugins as below

W3 Total Cache + CDN + WP DB Cache

It should able to deliver the speed you have been expected.

Installing memcache, apc and running it together with a suphp usually leads to all sorts of errors you don’t really want to have.

It has been fixed by my web hosts. For now, it’s suPHP running alongside memcache.

In case people stumble on this later…

Yes, memcache works perfectly fine along side suphp.

suPHP does not work with APC or any of the opcode cache tools. Thouch cpanel and other tools can enable this setting, at the implementation level, they are incompatible concepts.

“127.0.0.1:11211 may not running or not responding.” can be caused by memcache being down, the port being blocked, and loopback not being configured on the server.

netstat -tap will show if memcache is loaded.
ping 127.0.0.1 will tell you if the loop back is working
telnet 127.0.0.1 11211 will tell you if the port is blocked

And that’s all I have to say about that.

my 127.0.0.1 11211 has been blocked, what shouｄ　I do now/
