Problem uploading images to CMS

[MSS77]

Hello everybody

 

I have a big problem.

I'm trying to upload images to a CMS page, It should be easy but I can't.

When I click to upload url I go to the window of CMS root images (see image below), but I can't do anything, doesn't load well.

I can't copy, scroll, select image, upload, refresh, etc, nothing.

 

I have been seen maybe is tinymce or ajaxfilemanager, but I don't know how to solve it.

 

It's possible to install again tinymce (or other similar tool) automatically ?

 

I think it's a basic tool and I'm little crazy now.

 

I would appreciate any help.

Thank you in advance!!
