Hey there,
having somewhat similar problems to the people above, since your patch 2 days ago my wp-admin (i use wordpress.com) section continually refreshes and in so doing, forces the advertisement to re-appear. I mainly use google chrome version 62.0.3202.94. But i also tested to make sure it wasn’t my browser: Firefox 56.0.2. I’m not sure how to check my wordpress version outside of the code, which i can’t see because i’m locked out of the admin section.. The website itself still works, which leads me to believe the main problem is the forced pop-up ad (which i’ve never noticed before now, so i’m guessing it is new) which only shows in the admin section. The website in question:

I don’t believe any of the other plugins are the problem, since everything worked perfectly before, but since you asked, my list of plugins:
Master Slider (wouldn’t post this otherwise:P)
WordPress Charts and Graphs Lite
AMP
Akismet Anti-Spam
Goo Pie Chart
Jetpack by WordPress.com
Ninja Forms
Page scroll to id
Show-Hide / Collapse-Expand
Timeline and History slider
VaultPress
WP Google Maps
I’d love a fix, since my customer wants me to update something i can’t access currently without disabling the site’s slider, which understandably, he does not want me to do. Please help.
EDIT: also, since my page continually refreshes, i’m having no luck using the inspect tool/other tools that read data from the page, since again: it refreshes.
