Make sure you haven't enabled the domxml extension(the one we used on php4 in eZ Publish 3.x), only the standard php xml extension should be enabled. On Redhat / Fedora / CentOs, you have to enable it specifically your self.

If you read the post above yours, you'll see something about domxml aka dom extension should not be used with php 5.x.

Thanks for Your Help,
The problem seems not in the php5 dom extension, as long as we know, in php5 everything is embedded in the core,

In fact if we make a fresh Ez4.0.1 installation on the same machine everything works smooth.. so it should be a problem in the system update from 3.10.1 to 4.0.1,

We repeated step by step the upgrade and we found this issue,
Finished installing ezfind we have to run the updatesearchindexsolr.php to index content and we get an error similar to one posted on a forum thread named <b>php-cli probleme</b>.

Till this point all works fine apart ezfind of course, following the thread quoted above we try this command;

<b>bin/php/ezpgenerateautoloads.php -extension</b>

After this the system become slow and in the admin interface as I try to create a new object i get the error on topic of this thread,

Now.. We need ezfind, once you try it.. you can't do without, and ezfind seems stable on our enviroment with 3.10.1,

Do we stop there or we risk to update every site to 4.0.1 hoping that ezfind for ez4 series will be fixed in the next future?

Any further help is very appreciated,
Thank You,
Marco

Kristof is absolutely right!
If you are updating your eZ installation from eZ 3.x to eZ 4.x please check that all extensions using old DOM functions are removed from system.

In my case, we updated our system to eZ 4.0.1 but left old ezdhtml editor from eZ 3.10.
We tried to turn it of in extensions section and regenerate autoloads using "renerate autoloads" button.
But it didn't help. Than I take a look at /autoload/ezp_extension.php and noticed that
'advDOMDocument' => 'extension/ezdhtml/lib/advdomnode.php',
'advDOMNode' => 'extension/ezdhtml/lib/advdomnode.php',
'eZDHTMLInputParser' => 'extension/ezdhtml/ezxmltext/handlers/input/ezdhtmlinputparser.php',
'eZDHTMLXMLInput' => 'extension/ezdhtml/ezxmltext/handlers/input/ezdhtmlxmlinput.php',
'eZXMLInputParser' => 'extension/ezdhtml/ezxmltext/common/ezxmlinputparser.php',
'eZXMLSchema' => 'extension/ezdhtml/ezxmltext/common/ezxmlschema.php',
still were there, so I needed to remove them manuallly.

So please make sure that you removed them from autoloads. And use a new OE editor instead of old eZ 3.x version editor.

Best regards,
