Maybe you have you have turned on private browsing in Safari? I have quite a similar experience like you and the reason behind mine is that I accidentally turned private browsing on. The menu and tab bar is all dark with white font and you're always prompted to log in into sites even though you clicked the remember me button.
Have you tried updating both your email client app and your web browser? That sometimes helps, if it doesn't I would recommend you restore both those apps back to the default settings.
This is exactly what happens. I have zero tech skills so please walk me through the steps. I did go back to Safari to see where I should go but can't find where to turn on/off private browsing. Thank you so much.
I've forgotten to how to do it as well, so I made a little googling to remember it. Here's the You are not allowed to view links. Register or Login but all you have to go is to click the double square at the right hand side of your browser which will show you all of your tabbed windows stacked together. Scroll at the top then you'll see "Private" at the left side. Click it and it'll be turned off. Easy peasy.
Easy peasy when you know how. Thank you so much!!!!! That did it. Wow, I can hardly believe it. Hope you have a Merry Christmas and all the best for 2015.Thanks again.
