Unable to add cookies, header already sent

[ttiger]

Anyone know why I'm getting this error? Just had it happen out of the blue. I didn't change anything and the board was running fine before this.

Here is the error:
Warning: Invalid argument supplied for foreach() in /home/user1/public_html/forums/includes/sessions.php on line 266




Unable to add cookies, header already sent.

Either youve hacked somthing in sessions.php file incorrectly.

reupload a default version of includes/sessions.php in ASCII mode.

As I said before. I did not change a single thing. It was working fine and then woke up this morning and this happened.

I have already tried clearing my cookies several times, I reloaded all of the original vbulletin files and I tried doing a repair on the database.

If this is the case you should open a support ticket in the members area. you should include an admin account with full permissions and ftp access so they can take a look.

Language error, i'd check that your language table is off MyISAM type and not InnoDB type.

[ttiger]

I just checked all tables are MyISAM type except "session" which is HEAP type.

This is really strange guys, there's got to be something going on. Our board has been great since monday, woke up this morning, and I have same exact error.

[ttiger]

Well I guess its good to hear its not just me.

OK, after some searching I found Freddie's fixoptions.php, I had to alter it though, cause I think functions have moved around since he first created it. Here it is attached. Run this from your forums root directory and you'll be back in business.

[Nombie Wan]

Now, my questions is, what happened / is happening exactly? Sounds like there's still some sort of bug lingering. A fairly major bug if it leaves your board inoperable.

[ttiger]

Hey thanks man! Excellent job.

[Elyk]

Argh, same problem as above, ran fixoptions, still get same message for line 266 in sessions, cant add cookies, header already sent. Help!!!

Elyk, please start your own thread with all the relevant details, include the complete error message and everything you've done to this point.

There have been a number of threads about this.

I've had this problem seven or eight times since upgrading to vB3 beta last summer. It always happens during high server loads, such as during a mysqldump.

I'm now running Gold, and it just happened again, this time during normal operations, though still with an unusually high server load.

When I tried to run fixoptions.php, which always solved the problem in the past, I got:

"Rebuilding options
Fatal error: Unknown function: build_datastore() in /home/sf2/public_html/forum/includes/adminfunctions.php on line 1785"

I had to upload the adminfuntions.php from the RC4 build to get it to work.

They changed where the build_datastore() function is declared, now in /functions.php since gold. I added an include to the file and attached it above in my other post. That file will work with Gold.

Can we get an explanation from someone on this issue? I suspect it has something to do with cron. I run text and straight backups every night and I think these may be interrupting a vB cron job that runs this function. Not sure, but some insight would be great.
