Blank page after upgrade from 8.2 to 9.0 - found work around

[Rocologo]

Steps to reproduce

1. Upgraded 8.2 version to 9.0
2. After upgrade, the Personal Page and the Admin page did not work. They both showed a blank page.
3. I google the problem and found that it properly was one of the apps which was not 9.0 ready.
4. I therefor disabled all apps, which made the Personal and Admin pages work again.
5. I enabled the apps one after one and found that it was " External storage support 0.5.2" which caused the problem.
6. in the owncloud.log I could see that it was line 268 in google.php which failed.
7. I google that problem and found this solution
8. So I change the line from
   "if (empty($child->getFileExtension())"
   to
   "if ($child->getFileExtension()"
   and this fixed the problem. I could now enable "External storage support 0.5.2" and the Personal Page + Admin Page did work again.

Server configuration

Operating system:

Web server:

Database:

PHP version:

ownCloud version: (see ownCloud admin page)

Updated from an older ownCloud or fresh install:

Where did you install ownCloud from:

Signing status (ownCloud 9.0 and above):

Login as admin user into your ownCloud and access 
http://example.com/index.php/settings/integrity/failed 
paste the results here.

List of activated apps:

If you have access to your command line run e.g.:
sudo -u www-data php occ app:list
from within your ownCloud installation folder

The content of config/config.php:

If you have access to your command line run e.g.:
sudo -u www-data php occ config:list system
from within your ownCloud installation folder

or 

Insert your config.php content here
(Without the database password, passwordsalt and secret)

Are you using external storage, if yes which one: local/smb/sftp/...

Are you using encryption: yes/no

Are you using an external user-backend, if yes which one: LDAP/ActiveDirectory/Webdav/...

LDAP configuration (delete this part if not used)

With access to your command line run e.g.:
sudo -u www-data php occ ldap:show-config
from within your ownCloud installation folder

Without access to your command line download the data/owncloud.db to your local
computer or access your SQL server remotely and run the select query:
SELECT * FROM `oc_appconfig` WHERE `appid` = 'user_ldap';


Eventually replace sensitive data as the name/IP-address of your LDAP server or groups.

Indeed some older PHP versions don't like that construct.

So did you have a GDrive external storage then ?

[PVince81]

From what I see this is already fixed in v9.0.1

Yes, should be a duplicate of #22960 on PHP 5.4 (the used PHP version of @Rocologo is missing. Hinthint: Please always fill out the issue template completely).

Fix is in #22961 which gets shipped with 9.0.1

[Rocologo]

Sorry for not filling out the template. I will of cause give you all the info you need.

1. I don't have any connections to Google drive. I have only connections to my local storage (Samba).

2. I can confirm that I have "PHP 5.4.45-1~dotdeb+7.1" installed on my Debian 7.9 server. Im using "Openmediavault 2.x" which does not support the never PHP versions.
