As Ms. Cheshire has stated, when these types of errors appear, it's best to abide by their request(s) such as the "Log out and Log back in" error. Ye' can also try re-freshin' the page and see if that helps ye'. This occurrence does happen from time to time with us all but it's best to be patient, ma'am. I don't believe it's yer browser or any of the sort. It's most likely the forum itself decidin' to trip a little. Especially when so many users access it continuously throughout the day.
Thank you.
I sorted it out when I last time tryied to change it.
Turns out, the 're-fresh' thing worked.
Thank you, Vespian and Chesire. This thread can be locked now. :)
