I know this is an issue that's been affecting a lot of people recently. I'm struggling to reproduce this issue which makes it difficult for me to fix it, so if anyone who suffers this issue could follow the following steps it would greatly help me resolve it and hopefully fix it!
1) Use Chrome
2) Navigate to a page you are logged in on (eg scirra.com)
3) Press F12
4) A new panel will open at the bottom, click on "Resources"
5) Select 'Cookies' on the left
6) Click on scirra.com
7) There is a cookie with the name 'scirraLID'
8) Copy me it's value
9) Repeat steps for a url where you are not logged in (eg scirra.com/forum)
Then email me at tomepc@scirra.com along with:
1) Your username
Thanks if anyone has the time to do this!
IMPORTANT DO NOT POST/EMAIL YOUR COOKIE VALUE TO ANYONE ELSE BUT ME!
