TYPO3 Core

I can confirm this...

Thank you for your quick response! I've tried clear caches as described, but install tool detected many incompatible extension. I don't think, they are really incompatible, because I had no problems with them, also not under 6.2beta5. And: sometimes 1 extension was mentioned, sometimes 3 extension.

Now I have downgraded to 6.2beta4, but extension manager does still not work. Message appears is now:

Property TYPO3\CMS\Extensionmanager\Utility\ListUtility::$packageManager does not exist

ReflectionException thrown in file
/is/htdocs/wp11035062_LVJ7Z06IPY/www/typo3_src-6.2.0beta4/typo3/sysext/extbase/Classes/Reflection/PropertyReflection.php in line 47.

If I remember correctly, I've got the same message before downgrading and after clearing caches as described.

Do you have any idea how to get the extension manager to work again?

Hi Oli

Yes, that roundtrip solved the problem, thanks.

I have the same problem again after upgrading from 6.2beta4 to 6.2.2. "Clear all Caches" in install tool does not solve the problem for me - the error message still apears.

But: I'm using "APC cache backend" instead of "Database cache backend". If I switch back to "Database cache backend", then the error suddenly dissappears.

The solution for this problem is: writing a small php file which clears the APC-Cache:

<?php
apc_clear_cache ();
apc_clear_cache('user'); 
apc_clear_cache('opcode');
?>

Ah, there is already a button "Clear PHP Opcode Cache" below the button "Clear all Caches". I have not tested this button yet, but it will solve the problem, too, I think ;-)

Hi,

was this issue fixed with TYPO3 6.2.4 or does it still exists?

Or better, does the implemented "Clear PHP opcode cache" button helps?

Hi Alex

I'd say so. At least in the latest two 6.2.4 setups I had, I didn't encounter that one.

With the "Clear PHP opcode cache" button everything is fine!
