Error after upgrade : Unable to add cookies, header already sent.

[Mr.Mohammad]

Hello

After I upgraded to version (vBulletin 3.8.7 Patch Level 2) faced with a lot of error code

example, the following error:

Unable to add cookies, header already sent.
File: / home / iranmahv / public_html / showthread.php
Line: 2

I ordered via define ('DISABLE_HOOKS', true); disable all hacks, but I still did not resolve my issue.

Please help me Thanks

What version did you upgrade from, and what version of PHP do you have?

What version did you upgrade from, and what version of PHP do you have?

Upgrade from 3.8.7 to 3.8.7 pacht level 2

my php version : 5.2.17

That sounds good. I asked because some upgrades cause error messages with older versions of PHP.

I'm not sure what to tell you except to try uploading all the files again (assuming you haven't made any modifications to any files that you need to keep).
