For how long does the cookie for login stay valid? For some time now, I keep being logged off after only several minutes. Have you changed any settings on the server as far as cookies validity is concerned?
I log in via Facebook.
Please note that I'm not a teacher.
On the couple of occasions that I have clicked through via Facebook, I have been logged out after only a few minutes of inactivity. I have only found that the cookie remains permanent when I use the website direct on my laptop, via my internet browser and by actually going to English Language (ESL) Learning Online - UsingEnglish.com and logging in from there. The "remember my details" works fine there - even if I close my browser or switch off my laptop, when I go back in to the site, it has kept my username and password and logs me in automatically.
