Pagetree not shown due to error in TYPO3\CMS\Backend\Controller\Page\TreeController
0%
Description
After updating to 9.5.17 the pagetree is no longer shown due to the following error:
Core: Exception handler (WEB): Uncaught TYPO3 Exception: Cannot use object of type __PHP_Incomplete_Class as array | Error thrown in file typo3/sysext/backend/Classes/Controller/Page/TreeController.php in line 189
I could track the error down to the following:
$this->expandedState is an object but $this->expandedState->stateHash is not. Thus the condition in Line 186 results in false, leading to the assumption that $this->expandedState is an array. Which it is not and trying to retrieve stateHash via $this->expandedState['stateHash'] results in the mentioned error.
For my two systems removing is_object($this->expandedState->stateHash) from the condition worked but I have no idea whether this is a valid solution for everyone.
I'm guessing not, as the second part to the condition was added in https://github.com/TYPO3/TYPO3.CMS/commit/2a42940d6b21f9e134879c33b99a315953aa6742
Also, I have no idea why this issue didn't occur in versions between 9.5.1 and 9.5.17.

Thanks for the report. At least __PHP_Incomplete_Class is a signal that previously that was a (insecure?!) deserialization.
In case an object cannot be deserialized (due to policy), the result would similar to this:
class __PHP_Incomplete_Class#2 (1) {
public $__PHP_Incomplete_Class_Name =>
string(8) "stdClass"
}
Can you please mention the class name that is shown in your scenario (it's stdClass in the example above)? Thx in advance for your feedback!
I guess that those objects are left-overs from older TYPO3 versions which can be "purged" by resetting user-settings in corresponding module in edit and advanced functions tab. At the very end of that form there's the reset user settings to default state button.

Can confirm. Having currently 2 affected client systems 9.5.17 (all with a multi site setup) with described behaviour and some, but not all backend user (admin and regular editors) can't load page tree.
It's for sure related the user settings and resetting BE user settings solved the general issue as a quick fix.
So far I can say there is an issue in
$GLOBAL['BE_USER']['uc']['BackendComponents']['States']
all sub items (Pagetree, typo3-module-menu, typo3-navigationContainer) do have as a very first child an item of
"__PHP_Incomplete_Class_Name" = "stdClass"
As the values of $GLOBAL['BE_USER']['uc']['BackendComponents']['States'] get later mapped onto $this->expandedState['stateHash'] it causes the issue.
So quite sure it is a specific / maybe outdated user setting which causes the issue on deserialization.
OK, it seems to be already within the serialized back_users uc value in the database. Here you can see the relevant part of BackendComponents:
a:1:{s:6:"States";a:1:{s:8:"Pagetree";O:8:"stdClass":1:{s:9:"stateHash";O:8:"stdClass":3:{s:1:"0";i:1;s:4:"root";i:1;s:16:"lastSelectedNode";s:2:"p0";}}}}
This value is the uc part of an affected backend user untouched (not logged in after update, not simulated by an admin).
Hope this helps!

Having the same problem
clearing be user preferences multiple times with relogin did help
updated TYPO3 9.5.13 -> 9.5.17
we have multiple sites (pages with is_siteroot in folders below root page)
maybe related to https://forge.typo3.org/issues/91221 ?

As far as I can see there is already a solution within the install tool in class BackendUserConfigurationUpdate.
This seems to address exactly the issue.
Not quite sure in which version the additional migration task has been added, but it helps you solving the issue system wide.
Just got to module Admin Tools -> Update and select Update Wizard.
There you should see a new, not yet executed migragtion task:
Update backend user configuration array
The backend user "uc" array, which is persisted in the db, now only allows for arrays inside its structure instead of stdClass objects. Update the uc structure for all backend users.
Execute this migration task and your BE users will be updated and have a sane uc configuration in the end.
Problem solved and page tree can be loaeded again.
PS: An offical public note somewhere to this migration task would be highly recommended.

Please report back if the mentioned approach via that upgrade wizard solves the issue - if it does not, please provide additional details, what's still missing.

It happens to me too in latest Safari (macOS Big Sur) in TYPO3 11.5. Sometimes I can get it back by reseting user settings. Sometimes I have to reset Safari. I could not find the exact way when it happens or how to fix it (different ways at different times). Last time it was after adding yubico MFA. Before it was after I worked with direct_mail. I remember it also happened after looking to BE users module. So no stable reason really.
I have the following error in JS console:
[Error] TypeError: null is not an object (evaluating 'this.container.querySelectorAll')
