[Plugin: W3 Total Cache] TC do not detect user logout

Edit: Fresh WordPress 3.1.4 installtion with default theme and plugins.

Hi vugluskra!

Same problem here!
If set true any options like:

“Do not cache for logged in users”

W3TC will put the message “User is logged in” and not cache or minify HTML and CSS.

So strange and I have the same issue on all my sites.

I’m trying solve it with help of my webhost (Dreamhost) and they are doing the best to help me!

Do you use Dreamhost too?
Any progress in solving this?

Ps.: I’m not logged in when this message is showed.
Happens with any browser… even in other machines.

If you clear your cookies the problem persists? Can anyone still having this issue submit a bug submission from the support tab of the plugin?

The problem persists!
Even clearing the cookies! I’m logged in via Firefox… and problem happens with any other browser, and even in places with different IP address.

I’m trying other plugins cache… but none of them does the browser cache like w3tc.

Do you want me to setup an enviroment where you can see this happenning?

Sure, that would be great. Please submit a bug submission form with the details as noted above.

I’m having a similar issue with the Login with AJAX plugin. After logging out, ONLY on the homepage a cached page shows up, looking like the user is still logged in. The WP admin bar is still there. Go to any other page on the website and the user is logged out.

Hi Frederick…

Thank you for your help.

This site has this problem happenning right now.

https://www.dowordpress.com.br/

I’ve configured to “not cache page for logged in users”.
Try reloading the home then you’ll see the page cache being recriated each reload.

Only page cache is enabled.
Only w3tc plugin is enabled.
Last WP an w3tc versions.
Default WP theme.
Other plugin optios are default.

What other information would you like me to send?

And …
I did the bug report submission too … as you asked me to do. ??

“The support request has been successfully sent.”

Hi *,
do you have any news to the problem? I havew the same link. “After logging out, ONLY on the homepage a cached page shows up, looking like the user is still logged in. The WP admin bar is still there. Go to any other page on the website and the user is logged out. ” but the other way roung. If I trys to login, nothing happens, go the any other page I’m logged in???

HI deindean, Frederick…

All problems I was having with the w3tc was caused for malicious code inserted into my theme and WordPress files!

Problably my site were hacked by some infected templated I tested which caused all this issues with my sites.

I found the malicious code and reinstalled everithing from scratch. I tell the whole story here… it is in Portuguese, but I tested and Google translator can do a god job on it ??

Files that I found malicious code were: functions.php, searchform.php and hundreds of wordpress core fires. So, the theme can be mannually corrected… but WordPress must be reinstalled! I did it with dozens of sites… some days lost in it!

vugluskra: my problem was exactly the same you’re facing now… maybe it has the same cause.

Frederick, Thank you for helping with this!

I have similar problem with logout (Firefox 8.0).
I use W3 Total Cache and Theme My Login and other 30 plugins
When i change Authentication Unique Keys and Salt in wp-config.php everything started to work fine

I’m also showing the logout button, but when I navigate or refresh the page…it shows me logged out.

W3 Total Cache is browser caching the page and showing that I’m still logged in.

anyone found a fix for this yet?

Ivnus… please check your site for maliciuos code…!
I’ve seen this same issue with some customers and thar was my problem… reported above!

I’m suposing you have already tested with other browser and cleared cache and cookies, right?

The plugin really works fine…

This plugins does not work fine with other plugins that use ‘wordpress’ word in their cookie names.

I had same problem as previously persons. Quick story:
2 browsers: FF(10) and IE(9), WP 3.3.1
FF open wp page, login and enable W3TC – (cache user logged in is disabled).
Open front page, other pages, posts – Page Caching using disk: enhanced (User is logged in) This is good.
Open IE, user is NOT logged in, cleared caches, open pages – Page Caching using disk: enhanced (User is logged in) WTF? User is NOT logged in.

Ok browsed google for answers found this topic. Strange – no solution.
Tried to see myself why W3TC thinks that user is logged in. Looked for code where it echoed that he thinks that user is logged in and found that cookie name is checked if it starts with ‘wordpress’ text. BTW – developers aren’t really smart and good – some code is repeated twice and this is not best practice example. Ok I left this as is.
Hmm next question – why W3TC founds cookie with ‘wordpress’ start in cookie names? Quick press F12 in IE and use developers tools. I found that Polylang plugin sets last used language in user cookie. Yes it’s good for Polylang users, but breaks W3TC.
Who to blame? If register Polylang issue, then maybe there are other plugins that also use ‘wordpress’ start string in their cookie names? I don’t want to find them all.
If W3TC could change cookie name checking – maybe this could solve the problem? Sounds good.
Examined WP cookies when user is logged in and not logged in. Found that special wordpress_logged_in_{hash} cookie exists at the same time with wordpress_{hash} cookie when user is logged in and they both are absent when user is logged off.

File: lib/W3/PgCache.php
748: if (strpos($cookie_name, ‘wordpress’) === 0) {
changed to
748: if (strpos($cookie_name, ‘wordpress_logged_in’) === 0) {

File: lib/W3/Db.php
614: if (strpos($cookie_name, ‘wordpress’) === 0) {
changed to
614: if (strpos($cookie_name, ‘wordpress_logged_in’) === 0) {

Tested again with FF and IE – now results are much better and functionality looks not broken.

Now developers should reject or accept this change.
