Twitter Feed Setup

I have followed the process to try and setup the schools twitter feed for teh screens, but get this error in the log:
86896 17-11-21 11:19:32 CMS Twitter getToken Error contacting Twitter API: SSL certificate problem: unable to get local issuer certificate

ant help much appreciated!

That would most likely be curl error, please have a look here - Using Tickers, Forecast, Twitter and other external resources that make use of HTTPS connections

Brill thats worked, but how do i get the feed to slow down when i have it on the fade effect, no matter what value i put in the speed, it changes every 1 second.

I feel like I replied to that question yesterday - Twitter scroll - 1.8.1
