I have made the 7.8.1 update and everything is ok right now.
Thank you for your help.

Thank you but it doesn’t work anymore.

> The memory allocation is up to 64M
> All the plugins are desactivated
> There’s no child theme and no caching plugin

Right now there’s no waiting wheel, but VC doesn’t display any layout.

What to do now???

here’s a printscreen:

When I go over the spinning load animation with the mouse , the path indicated on the left bottom corner is: vc.wpbakery.com/?utm_campaign=Vcplugin&utm_source=vc_user&utm_medium=backend-editor

Here are some informations, but please note the website was ok just a few days ago and it’s a standard OVH multi-site web hosting:

PHP version : 5.3.29
max_execution_time: 120
max_input-vars : 2000
SUHOSIN intalled: false
WP Memory Limit : 40MB/request (we not use Woocommerce)

If you want me to ask for something else, please give me more informations about the requirements.

I guess it’s rather a problem of activation or authentication.

When I have reinstalled the files (via Filezilla – the original files – for I hadn’t a backup) I had’nt to activate the Newspaper’s theme (there was no “activate theme” box area for the purchase code), is it normal?

I have also changed the admin’s pass.

The website is : http://www.aux4vents.org
I can give you the WP access.
