HTTP methods MKCOL and DELETE return error 501 Not Implemented

Server
1

Hello everyone,

I have installed my ownCloud server (10.0.2) on a shared web hosting service. Some features, like creating a folder or deleting a sharing, are not working.
In both cases, the HTTP request returns an error “501 Not Implemented : The requested method is not implemented by the server.”
It’s as if there was a reverse proxy blocking HTTP methods like MKCOL and DELETE, but I don’t think there’s one installed.

I’d be grateful to receive some help, unfortunately I’m totally lost…

Steps to reproduce

  1. Log as admin on my ownCloud web interface
  2. Try to create a new folder / try to delete a sharing

Expected behaviour

The folder is created, the sharing is deleted.

Actual behaviour

The folder is not created, the sharing is not deleted.
In both cases, the HTTP request returns an error “501 Not Implemented : The requested method is not implemented by the server.”

Contact your provider about this or use a real vserver. :slight_smile:

In case that would be helpful to someone else, the solution was given to me [here] (ownCloud - hébergement mutualisé : requêtes HTTP DELETE et MKCOL bloquées - PlanetHoster | PlanetHoster Forums).

It’s in french, so here’s the trick:
I had to add the following lines in the .htaccess file at the root of my ownCloud directory:

<IfModule mod_security2.c>
SecRuleRemoveById 1234123435
</IfModule>

The explanation might be found in this over post.
