Getting "Invalid Session" Error when attempting to

[GetOutOfBox]

When trying to send PMs on the forums:

"Invalid Session. Please resubmit the form."

I just assumed it was a cookie glitch at my end, so I logged out and cleared my cookies. Still here, the problem started yesterday for me. I googled around, and apparently there's a fix that must be done on the server end.

Here's a link to the fix:

I believe this is a phpBB based forum, so this should fix the problem for anyone experiencing this issue.

UPDATE:

I'm also seeing the following error randomly in some sub-forums at the top of the page:


"Warning: Cannot modify header information - headers already sent by (output started at /var/www/html/sourceop/themes/hl2/theme.php:219) in /var/www/html/sourceop/modules/Forums/viewtopic.php on line 572"

What url do you use to get to the website.

[GetOutOfBox]

sourceop.com

[GetOutOfBox]

The fuck, PM works now, but still getting the random errors embedded at the top of the screen, but they don't appear to be causing problems.

If the problem starts up again, I'll repost.

So you don't have www.? Is it any better with?

[GetOutOfBox]

PMing worked again for a while, then proceeded to stop working again.

I've tried accessing the site with the www prefix and without it, to no avail.

I also just tried clearing cookies, cache, etc again and it still didn't fix the problem.

UPDATE:

I just had a thought and tried the link to the TF2 Items forums I have bookmarked, and then viewing my private messages from there, which oddly enough seems to work consistently.

I'm not going to post the link I used here in case it contains my session id, which I don't want some random user hijacking. I'll PM it to you Drunken.

Yes, you'll have to login using www.sourceop.com and none of the other domains.
