Are your folder/file permissions correct and the folders belong to the correct user/group as well?

You can use Admin Tools to correct your file permissions.

Hello, thanks for the reply.

All the permissions are correct in the Joomla backend when I check them in the directory permissions section.

Are there any other permissions I should check?

Regards

Wayne

The folders appear writable.

Use your FTP client to check whether the subfolders and files belong to the correct user/group. Finally you should ask some advice from your hosting provider as well.

Hello,

The user groups look ok.
The Joomla Media Manager works fine, so I really dont think that permissions are a problem?

The hosting company dont support 3rd party applications which is understandable.

It is only K2 that is exhibiting this problem.

Can you list the specific folders that the K2 uses please? Also what permissions K2 requires on each of those folders/subfolders?

Then I can double check those folders.

Many thanks

Wayne

K2's media manager uses the /images folder but you can also change that.

The files should 644 and the folders 755.

Make sure to check the user/group ( not the Joomla! user, the file owner and group).

I have tried everything as mentioned, But still I get the error. Can you please provide some help? Thanks

Use your browser's developer tools and check the XHR requests made. Open the requests and check their response. The response should be JSON output. In your case you should see some PHP warnings mixed in the output breaking the JSON format.

Same Problem here
Over night, the Media Manager dont show correctly

Now it works.
I guess this is a Google Api-Problem, because the GApis don't load for a short time

@fred holla

I don't think that this was related with Google APIs at all. However i am glad you solved it.
