I am having troubles getting the digital dice to activate when creating a character...When clicked to activate, it slides over and then returns back to off position...Is there a way to fix this??

Are you running any ad/popup blockers, browser extensions, or a VPN? One of those is most likely interfering with DDB.

I have went through my browesr settings and even went through my computer and turned off everything I could and even added DDB to allow pop ups...But still the same is going on...Got any suggestions??

I am having the same issue for about a week+ and there was another poster who also posted about having this issue. 

A strange thing for me was that the die roller was working on 1 pc but not others after I had relinked my account to my email (as requested by D&DB) then my GM went in and saw that PC had a working die roller (and my others were not) and when I went back and tried that PC I could not get the die roller to work.

Good Luck to you and I hope it gets solved soon.

I think the issue happed for me right around the time of the buy out by WotC.
