if I generate a Workspace Preview Link and call it in the frontend, the correct WS version of the webpage is shown.
If I now call the URL WITHOUT the "ADMCMD_prev" GET-Parameter, the ADMCMD_prev cookie is still set.
The page now still shows the Workspace version and not the live.

  • PHP Version set to 5.6

this is not a duplicate, because I'm talking about accessing a page in the live workspace/without BE login, which ALSO has a valid preview-Link in one of the workspaces.
Steps to reproduce:

- modify page in workspace and create a preview-Link for it using the "Workspaces" module
- click the generated preview-link in the popup to access the page version once and set the cookie
- log out of backend
- access the same page's live version
-> still the preview-Link version is shown WITHOUT any notice, that you still see the preview-Linked version

This is very odd for submitting changes to the customer etc.

Plz re-open this ticket and investigate.

I think I have just seen it with TYPO3 7.6.16:

1) I tried to access the LIVE version of my site and obtained an "Oops an error occurred!" without any further explanation (even with config.contentObjectExceptionHandler = 0 )
2) clearing all cache did not work
3) Log error

Core: Exception handler (WEB): Uncaught TYPO3 Exception: #1294585192: ADMCMD command could not be executed! (No keyword configuration found) | Exception thrown in file /Volumes/Macintosh SSD/TYPO3-dists/typo3_src-7.6.16/typo3/sysext/version/Classes/Hook/PreviewHook.php in line 292. Requested URL: http://typo3.7.test.it:8888/index.php?id=1

4) Some days ago I had generated some preview links of a workspace
5) There was a ADMCMD cookie set
6) After deleting it the site was visible again

Is this issue still open?

Getting nearly same problem when sending preview links to editors. They wonder why their before opened tab, are not running any more, and plugins like indexed_search and others are showing an error.

(TYPO3 8.7.9)

#7 Updated by Masod Mohmand almost 2 years ago

  • TYPO3 Version changed from 6.2 to 8
  • PHP Version changed from 5.6 to 7.1

Same problem here. Is this solved?

The only way to leave the preview session is to remove the cookie. And the only fix for TYPO3 in v8 is to render a big button in the frontend that says "leave preview session". In TYPO3 v9 these issue a partially tackled with new features related to routing and URL handling in the core.
