When I used auto-update to get Google Analytics for WordPress 4.02 from v 4.0, Lightbox 2, which is used to overlay images on the current page, stop working.
The only troubleshooting I did was to disable Google Analytics for WordPress 4.02. Then Lightbox 2 worked OK.
I went back to Google Analytics for WordPress 4.0 and Lightbox 2 worked OK with it.

Can you please tell me what site you were using this on? It seems a bit weird for GA to break Lightbox...
Joost, thanks. My site is lesliewong.us/blog
I tried the 4.04 Google Analytics for WordPress and I get the same error with Lightbox 2 that I received with any version >4.0.
I see you're running it now though? Not having the issue anymore?
Joost, I was running v4.00 when you checked.
I installed 4.06 and it works with Lightbox 2 v.2.9.2
Thanks.
