clicking the post response button and turns out that you were logged out

and this just happened like seconds ago. i was posting a comment on the post ive found and have written so much about it. when i clicked on the post comment after the loading thing, it showede me a sign up page for mylot. that is when i realized i got logged out from the site automatically and the post i wrote was not posted after all. now i forgot what i said and i felt lazy to do it again. it pissed me off! haha.. but what can i do? nothing anymore so what i did was look for other topics for me to answer.
