TYPO3 Core

The same blocker of the EM in TYPO3 4.7.7. Nothing goes any more with the EM:

Fatal error: Cannot unset string offsets in /var/www/html/demo-franz/typo3_src-4.7.7/typo3/sysext/em/classes/tools/class.tx_em_tools.php on line 382

Here the backtrace and the parameters debugged:

Check your installations of irfaq!

The file ext_emconf.php contains the line:

'conflicts' => '',

This must be set to an array.

array (
        'depends' => 
        array (
            'php' => '4.1.2-6.0.2',
            'typo3' => '3.6.2-0.0.0',
        ),
        'conflicts' => array(),
        'suggests' => 
        array (
        ),
    ),

as i added the patch above it would be nice, if one could push it to gerrit ;)

Hi Kay, I just tested your patch, but it causes some warnings regarding incorrect usages of implode() and array_keys().

can you add the warnings here?

thanks
