We have upgraded to PHP version 5.3.14 and have the same problem. I read in the [TYPO3-german] mailinglist there was a discussion that it could be caused by the different behaviour of json_encode(). See http://lists.typo3.org/pipermail/typo3-german/2012-June/086261.html and https://bugs.php.net/bug.php?id=61537

What happens if you clear all filters? (Button in your screenshot)

We have
Apache/2.2.16 (Debian)PHP-Version:5.3.14-1~dotdeb.0
and a new setup up of typo3 4.7.2 works on the server - it happens only when I update a 4.6.x to a 4.7.x version
And yes - I did a version update ;)
The new empty setup and the updatet version share the same source via symlink.
Guess there must be something going wrong during the update...

I can clear the filter or choose any possible option - nothing changes - still empty.

I don't know if this has something to do with that bug, every time I call the extension manager I'll gett this logged:Core: Error handler (BE): PHP Warning: json_encode(): Invalid UTF-8 sequence in argument in /var/lib/typo3/typo3_src-4.7.2/typo3/classes/class.typo3ajax.php line 275

For me the workaround of the German mailinglist works fine, so it is definetly something in the data passed to json_encode function. Maybe $this->content needs to be cleaned before json_encode is called? I have not yet figured out the invalid UTF-8 sequence inside $this->content.
I attached the workaround of the mailing list to use __json_encode function if json_encode of the new php version does not work due to an invalid UTF-8 sequence.
We use:
PHP 5.3.14-1~dotdeb.0 with Suhosin-Patch
Typo3 4.6.10

I installed a new site on the same server. Source symlinked with the same source code as the site there the error occured. Transfered the database by sql - and everything is fine now.
So it can't be something with php - same server, same version. Same plugins - I don't know why it works now. But it is reproducable...

The charset of a file ext_emconf.php was not UTF-8. If there are special characters, then it comes to this error.
I converted the file and the problem was solved.

Confirmed, also for me it was one ext_emconf.php file that was not utf8 encoded and thus broke the json_encode(). Maybe there is a possibilty to show an explaining error message if this occurs?
With the utf8 encoded ext_emconf.php everything works fine for me again.

Hi,
does the problem still exists within newer versions of TYPO3 CMS (6.2.9)?

Hey. I'm closing this issue: It will no longer be fixed in 4.5 and does not happen in 6.2.
