I use Hades theme from Themeforest for our site http://socialjusticesolutions.org, when Subscribe 2 isenabled, the news ticker stops moving. I love the plugin, was hoping someone might have some info on this.
Try using the built-in widget would be my first response, this will avoid any coding error related issues. It will also ensure that the side bar code remains as HTML valid as it can by using the correct sidebar markup for your theme.
I have tried that, but to demonstrate I set it up with the plugin, and Ad Inserter deleted. Perhaps you could check it out? This only started after I updated to 3.5, before then the News Ticker was working fine. Incidentally, the news ticker isn’t the only thing that breaks when I enable S2, SimpleModalLogin, no longer works as well.
Figured it out! When i uncheck Enable AJax style subscription form, the ticker works again. Simple Modal works as well. Not sure what is going on, but I hope it helps you. Thanks for the plugin, it’s great!
