Unlimited loading

I am just starting to use OwnCloud and when I go to the main menu where I should have my files, I have unlimited loading and unable to upload any file. Namely that there is no file already present, and that due to the loading, I cannot add a file either.
When I look at the console it is noted this following error:

Failed to load resource: the server responded with a status of 501 ()
Uncaught (in promise) TypeError: Cannot read property ‘getElementsByTagNameNS’ of null
at Client._getSabreException (client.js?v=551b3844162d44e93382c25e8c5bd0da:430)
at client.js?v=551b3844162d44e93382c25e8c5bd0da:494

Could you help me please ?
Thanks in advance.


Hi Flavien,

unfortunately this is too little information, with the Error you provided, we cannot even guess.

There was an issue template when you started the topic. This is there for the good reason that without knowlege of configuration, logs etc. it is almost impossible to track down errors. Especially the owncloud.log gives information, why the 501 happened with your call.

For your convenience, here are the most important parts from the issue template again:

Server configuration

Operating system:

Web server:


PHP version:

ownCloud version: (see ownCloud admin page)

Updated from an older ownCloud or fresh install:

Where did you install ownCloud from:

List of activated apps:

Are you using encryption: yes/no

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


ownCloud log (data/owncloud.log)

Insert your ownCloud log here

Browser log

Insert your browser log here, this could for example include:

a) The javascript console log
b) The network log 
c) ...
