Error Message When Navigating Thread

[schrodinger]

I'm having a recurring issue when trying to click on "Next" or the next page number within a thread.  An error box pops up that says "JS Error: ReferenceError: adServer is not defined".  I don't get directed to the next page and the entire thread navigation bar becomes unclickable.  I have to click back to the Main Board, then click directly on page number I want to view.

The problem only occurs on my computer browser (Chrome) and not on my phone (Safari).  I've tried toggling AdBlock on and off and it doesn't seem to make a difference.  I've done the usual deleting cookies and clearing cache with no impact.
