In Drupal 7.63, I am trying to add a new rule, however I am being greeted with a WSOD. I am doing the following process...
- Create a new Rule
- Add condition
- Select any condition from the drop down list
I then receive a WSOD with the following error in my browser console log:
Preceded by the warning:
[Deprecation] Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user's experience. For more help, check https://xhr.spec.whatwg.org/.
I can see that other people have had this error in the past here, however I cannot see a solution to this. Similar to the referenced link I also have Advanced CSS/JS Aggregation installed (defaulted to jQuery 1.4.4).
Any help would be appreciated.
