403 Forbidden on edit slides

Here as well.
When create multi slide all fine, but if I enter a slide to edit or if i create a single slide the issue occurs..
I’m running it in a multisite wordpress installation, I installed your plugin on the network.
I tryed localy with one site, the same theme and the same plugin on the network and all is fine.
Maybe some fault in the configuration?
https://www.notizieplus.it is the site, WP 4.1.4, plugin ver. 1.5.3 if you need more I’m here.
Thanks for the answer.

Thank you for your posts and sorry for any inconvenience caused.

I see that @tobeplus created a thread on our forum here: https://tribulant.com/forums/discussion/1835/403-forbidden-on-edit-slides

We can continue the discussion there if it is okay?

Yes, we can discus here if you please.
I try to deactivate all the plugin on the network and reactivate one by on, no change.

Having the same problem when clicking save after editing a single slide.
