TYPO3 Core

I can not confirm this - it works fine here on my local dev system (debian / TYPO3 3.8.0 / PHP 5.0.5).
Could you please post the error message?

Please, do as Rupert suggest and post the messages. TYPO3 is supposed to run on PHP 5.0.

Known problem in php 5.0.5 is:
"Fatal error: Only variables can be passed by reference in..."
In Typo3 this problem occurs in t3lib/class.t3lib_timetrack.php, line 368:

$theLabel = $flag_tree ? end(t3lib_div::trimExplode('.',$data['key'],1)) : $data['key'];

If you "extract" the paramater:
$tmp = t3lib_div::trimExplode('.',$data['key'],1);
$theLabel = $flag_tree ? end($tmp) : $data['key'];
It works.

No other problems with this combination of php 5.0.5-3 (debian) and typo 3.8.0 found till now on my installation..

Unfortunately there where no error messages.
The mentioned problem with page header edit only reloaded the content of that frame (page content view) as if there where no get variables...
after setting the settings of my hoster hosteurope.de to

PHP-RegisterGlobals off
PHP-Magic-Quotes-GPC on
PHP-Zend-ZE1-Kompatibilität off
PHP-Register-Long-Arrays on
PHP-Session-Use-Trans-SID on
PHP-Allow-Call-Time-Pass-Reference on
PHP-MySQL-Secure-Login off

the backend worked as normal as before.
Unfortunalely i have not written down the settings before
changing them.

Strange.

The problem in t3lib_timetrack.php that Julian reported has been fixed in CVS.

Christian, can I close this bug? We can reopen the bug or file an new one if you can give us more details about the PHP settings.

As i can not provide more info and the installation is running fine with the changes mentioned, you can close this bug.

Closing the bug because no moe info is available.
