Post Grid 2.0.40 interfere with other plugins

Hi,
I updated today to 2.0.40 and have similar problems to Jessica:
- Duplicator Plugin doesn't work: If you click on buttons, nothings happen
- Cache plugin "WP Fastest Cache": if you click on "Delete cache" in the admin bar, nothing happens any longer.
If I deactivate Post grid, everything works.
With the former version of Post grid there wasn't any problem.
It would be great if you could solve it quickly.
Thanks.

Nathalie
