phpBB : Critical Error

Error creating new session

DEBUG MODE

INSERT INTO phpbb_sessions (session_id, session_user_id, session_start, session_time, session_ip, session_page, session_logged_in, session_admin) VALUES ('1f7f7f406e08ce75dd50e1ed4ea9684c', -1, 1153213189, 1153213189, 'd4b50864', 36, 0, 0)

Line : 213
File : sessions.php

Refreshed the page and it worked, i also got problem if i have
your page open for some houers and then try to open another
page on this page, then it also be some problems like
"not finding bla bla error" message, refresh and it works
Is that something you know about ?

Why should it be dissalowed in the
robots.txt

Disallow: forums/post-*.html$
Disallow: forums/updates-topic.html*$
Disallow: forums/stop-updates-topic.html*$
Disallow: forums/ptopic*.html$
Disallow: forums/ntopic*.html$
?
Isen't that the posts that get dissalowed then ?

Sorry if it is stupid questions that i ask.. =P
