Furthermore – it doesn’t seem like you can deactivate this plugin. I emptied the page cache and deactivated the plugin and all pages get a 404 error. Reactivate it and the page appears.
What gives?
Are you logged in while testing? As for the 404s that’s hard to guess without a bug submission as that is not a known bug.

I am logged in while testing (firefox); however I’m using another browser to perform the tests (IE8).
I will submit a bug report on the uninstall thing.
Using ctrl + shift + del can you clear your cookies and let me know if the issue continues? If that fails can you check wp-content/w3tc/pgcache/ and see if any files are being written?

Did the cache thing, even used Google Chrome which had never been to the site – same issue. As for directory, no files are being written – even when the plugin is active. When the plugin is active – all pages will load. When plugin deactivated – only homepage will display – rest of site generates 404 error.
One or more of the following is true:
- There’s some files missing from the installation. If you cannot activate / deactivate without fatal errors files are missing or permissions are in fact not ok.
- There’s “interference” from another plugin (try to disable all except W3TC to confirm).
- You have another caching plugin of any type installed (even if activated)

I sent a bug report so you can check this yourself. If you look at the bug report, you will see:
1) Can’t say what is/isn’t missing from installation – but I can activate and reactivate the plugin no problem. Active, site works but doesn’t cache – inactive, site doesn’t work except homepage.
2) Per the bug report I submitted – ALL plugins are deactivated and defualt WP theme active.
3) See #1, no plugin active. In fact, no other cache plugins installed. WP Super Cache was installed, but I deleted prior to installing this one. That plugin directory no longer exists.
Have you looked at the bug report I submitted? BTW, does this plugin have a log file?
For some reason, mine said: Status Cache: not-enabled (not logged in) but when I deleted all my cookies/ emptied cache, It was fine.
Also I notice that my
wp-content/w3tc/pgcache/
folder is empty. Is this normal? I am using the memcache settings for page/minify.
Also, My site gets reallly slow when I use database caching (after I update posts/pages etc). Is this because my free memory on my server is only like 30 megs (with it DB cacheing disabled)?

If you’re not using disk method for page cache (as you said), then yes it’s normal.

Free memory is irrelevant.
If you’re using memcached for DB caching and you haven’t installed the PECL Memcache PHP extension, then yes this can happen. If you’re using disk, then you have a “slow” disk array / excessive queries / an optimized theme.
For best results (if you have a single standalone server), use APC as your DB caching method and adjust the SHM size accordingly.
Thanks for the answer. I wasn’t sure If I needed to change the write to wp-content/w3tc/pgcache/ to 777, so I guess I can change it back to 755.
I am using a VPS. So will I be able to install APC? And what is SHM size, and how to adjust it.. what are the proper parameters etc..?
How can I verify that PECL Memcache PHP extension is installed? I am running debian (is the command something like memcache -v ?).
Can you refer me to any tutorials on how to install APC or memcache?

Right

Yes. So choose a value, then copy the file apc.php to some location you can open in your browser and check it after 6-24h and see if you have some available memory left or and very little fragmentation. If there’s a lot, lower the SHM, if there’s not do the reverse.

For a standalone server you don’t need it. Go to the installation tab or read the FAQ tab of the plugin to learn more.

Go to the installation tab of the plugin.
I’m having the same issue as d4jaj1 when I deactivate the plugin (all pages load when activated, only the homepage when deactivated).
Was there a resolution to the issue?
The cause of other issues in this thread are likely not related to your situation. Are you using disk enhanced mode? Are you using fancy permalinks? Did you check your WordPress .htaccess directives after deactivation?
