That’s odd. Best thing to do now is dive into the code and debug it yourself. Look in wp-cache-phase2.php in the wp_cache_is_rejected() function. I’m afraid you’ll just have to use error_log or wp_mail() to send you info when a request is made.
I also tried everything but couldn’t make it work.
I deleted PHP speedy completely from my site.
The gzip output if off
permalinks is on
I installed the latest version yesterday.
I have turned on logging but no errors are being thrown and it shows ‘WP Super Cache’ as ON but still 0 pages cached as shown below:
Cache Contents
WP-Cache (0KB)
* 0 Cached Pages
* 0 Expired Pages
WP-Super-Cache (0KB)
* 0 Cached Pages
* 0 Expired Pages
Don’t know how to fix this on my WP 2.8.4 installation.
Thanks
Odd, the debug settings should have showed you why it wasn’t working.
Same story here. Using version 0.9.7.
Tried enabling email and file logging – neither worked. Didn’t get any emails and the file that it says it’s currently logging to not even being created. The wp-content/cache/ is chmoded to 777.
My wp-content/cache folder is 755, could that be the issue?
But I cannot change it to 777, I think because wp-supercache has created it because i see these folders under it:
/blogs
/meta
/supercache
.htaccess
Bizarre. Any plugins or themes using the output buffer? Look for the command ob_start() in your plugins and themes folders. Have you tried the plugin in half-on mode?
I have a plugin that uses output buffer. Can’t disable it right now though, to try without it. Half-on mode doesn’t work either.
It probably is a plugin. I experienced the same 0 cached files problem when I activated the wp-minify plugin. It was a problem in wp-minify where the output buffer wasn’t set up because of a bug in the theme. (Complicated eh?)
Anyway, I fixed the problem in wp-minify and the author has been DMed so hopefully the next version will include the fix.
I’ll try disabling it some time when traffic is low. I’m using output buffer to insert widgets within content areas via shortcodes. The 2.9 has this in the core, but earlier versions don’t have this function.
Will post the results.
I haven’t added any new plugins, but I did upgrade to the latest version of WordPress. Then Supercache stopped working except for feeds.
I found the solution:
defined WP__CACHE before require_once(ABSPATH . 'wp-settings.php');
saeidzebardast – the plugin should have printed an error message about that but I found an error in the logic that I have just fixed. Glad it was something simple!
Hello, I have experienced the same problem as well. As per the solution recommended by saeidzebardast, will this fix be included in an update for the plugin or is this a change I would need to make manually? If so, where specifically would I make this change?
Thank you!
smoke489 – read the readme.txt that comes with the plugin. The WP_CACHE define is in your wp-config.php
Hello, I have the same problem mentioned here, I think I have followed every trick I could find on this topic, but nothing still gets cached.
I’m using WordPress 2.7 with wp-super-cache 0.9.7
I have all write permissions granted to the webserver user, required files were correctly created in wp-content by the plugin itself, cache/supercache are both 777, .htaccess files match what’s in the plugin admin page (both the one in the webroot and the one in the cache dir), WP_CACHE is defined, PHP safe mode is disabled… I don’t really know where else to investigate – no change I made moved me from 0 cached pages.
The site is struggling and I really could use help from caching.
Thanks in advance for your help!
