Page History Slider is not working (security token was not present in the request)

[Vincenzo Parrello]

Goodmorning all,

since a couple of day, the add-on "Page History Slider" is not working properly.

No matter witch page I select, when I select the option "History (Slider)" I get the message:

ERROR: Your request could not be processed because a required security token was not present in the request. 
You may need to re-submit the form or reload the page.

All pages in all spaces faces this issue. Is the add-on no more compatible with my confluence? If it still compatible with my confluence, what could this error be related to?

Add-on name: Page History Slider
Add-on version: 1.3.1
Add-on key: net.customware.confluence.page-history-slider
Confluence version: 6.11.1

I know this is an old question, but I had the same issue and found it to be incompatible with my version of Confluence.
