What's the actual issue? That the link was expired or that you saw a page even after the link expired?

The problem is that I get an error message when visiting a page of the LIVE site that had been edited in a workspace before. The expected behaviour would be that the system displays the live version.

i just had the same issue in a test installation (4.5.3).
A few days ago i tried different settings with the workspaces. Today i logged in, just tried to show the page and got that error.

Sorry, i did not checked the cookie, just deleted it. Now everything works fine.

Sorry I'm not able to reproduce this - is this still valid?

Hi..

I just was able to reproduce it ( at least some kind as the error is different, but seems related to it ).
( Typo3 version 4.6.7 )
Here are the steps:

- Created a new Workspace
- Modified some things in the workspace
- Generated a preview link for that workspace
- After the Link has expired the entire frontend just shows "Oops, an error occurred!"
- Removing the coockie named ADMCMD_prev everything is ok again.

The coockie:
Name: ADMCMD_prev
Content: 5868c49194cb392b306678d1a51a6b6f
Domain: ********
Path: /
Send For: Any kind of connection
Accessible to Script: Yes
Created: Sunday, April 8, 2012 5:06:59 PM
Expires: When I close my browser

So the bugfix in my eyes would be so set a specific expiredate for the coockie and not "When I close my browser" as I did not close my entire Browser, which in real happens maybe once a week or even more seldom.

Still a problem with 4.7.x and I can confirm the same symptoms as prior comments.

After deleting the cookie, the site works again.

A solution could be to either put the expiry time on the cookie to be the same as the preview link or a better verification of the cookie by TYPO3 when it's evaluation it.

This is some advanced ** but hopefully I can look into a patch soon. Anyone else wants to help out?

Got that error in 4.5.29, Chrome 19, but not n Firefox. Same symptoms as above. Removing cookies solved the problem.

I got the same problem today.

Chrome works ( 30.0.1553.0 (209444), there was no cookie set )
Firefox ( 24.0 ) does not.

Typo3 4.7.15

Steps: Installing workspaces extension, followed a preview link some days ago. Afterwards
regular browsing of the site without using that link again.

Cookie ADMCMD_prev. Removal led to normal function.

-> Why does a cookie change the behaviour of my browser when I just visit the same
site ?

I just had the same issue with TYPO3 6.1.7 and workspaces 6.1.0.

As in the other cases, removing the cookies solved the problem, but before the entire website was not available for about one day.

Still present in 6.2.*

The expected behaviour should be:
if hte cookie is not valid anymore,
just show the live site instead!

This fixes the problem, but I honestly don't know if this could have unwanted sideeffects:

typo3/sysext/version/Classes/Hook/PreviewHook.php
#198ff

            } else {
+                if (isset($_COOKIE['ADMCMD_prev'])) {
+                    unset($_COOKIE['ADMCMD_prev']);
+                }
-                // throw new \Exception('ADMCMD command could not be executed! (No keyword configuration found)', 1294585192);
            }

We added a hook to our base-setup to fix this issue until this bug gets fixed.

ext_localconf.php:

// This is really user-unfriendly
// @see https://forge.typo3.org/issues/18761
if (\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::isLoaded('version')) {
    array_unshift($GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['tslib/class.tslib_fe.php']['connectToDB'], 'Vierwd\\VierwdBase\\Hooks\\VersioningHooks->removeExpiredPreviewCookie');
}

VersioningHooks.php

public function removeExpiredPreviewCookie() {
    if (isset($_COOKIE['ADMCMD_prev'])) {
        // check if the cookie is valid. if not, delete it
        $inputCode = $_COOKIE['ADMCMD_prev'];
        $where = 'keyword=' . $GLOBALS['TYPO3_DB']->fullQuoteStr($inputCode, 'sys_preview') . ' AND endtime>' . $GLOBALS['EXEC_TIME'];
        $previewData = $GLOBALS['TYPO3_DB']->exec_SELECTgetSingleRow('*', 'sys_preview', $where);
        if (!$previewData) {
            // remove cookie
            unset($_COOKIE['ADMCMD_prev']);
            setcookie('ADMCMD_prev', '', 0, GeneralUtility::getIndpEnv('TYPO3_SITE_PATH'));
        }
    }
}

Is there any progress on that issue? We still experience the behaviour on 8.7 LTS installations.
