i have a site problem and i don't know how to fix it. i've been a long time member, but i don't normally log into the forum as i tend to read via a [non apple] phone. however, i've been persistently presented with a security warning about the site's certificate not matching. i've tried, but can't figure out how to create a screen shot, but this is what the warning says: ____________________________ there are problems with the security certificate for this site this certificate is not from a trusted authority. issued to: common name: *.twitter.com organization: twitter.com issued by: common name: geotrust ssl ca organization: geotrust, inc. validity: issued on: 08/27/2013 expires on: 10/28/2017 ____________________________ i also see an intrusive ad that scrolls along as i scan forum listings or threads. sometimes it is a replication of the one across the top, but sometimes it is different, with 'otterbox ads' being the most common. fwiw, i have reset the device and i still have both these issues. (this problem does not occur on the desktop which is an antique apple imac with ad-blocking). any advice on how to fix this problem would be greatly appreciated. many thanks!
