First of all excuse me, I use Google translation to write this post.
When I activate WP Bakery there is a bug in the admin editor. I can not create a page anymore and sometimes I can not edit the information in the administration editor.
How can I fix this problem?
Thank you for your answers.

I thank you Elise for your involvement but this solution does not work.
I deleted WPBakery and Slider revolution and reinstalled these 2 plugins with the versions you put on my account.
The creation of a page is still not possible (same picture as the one above)
