class_core problem
 

This is the error message:

Unable to add cookies, header already sent.
File: /home/weusecou/public_html/upload/includes/class_core.php
Line: 3243

Now this is really not hurting anyone, it's just really annoying. Users are still able to post, and it is only happening to some users, not all.

We just migrated to a decidated server, and this started happening.

I did read some of the vb.org threads about class_core errors, and they recommended turning off plugins. Should I start doing that, or could it be related to our new server move??

Thanks

Everytime I've seen this "unable to add cookies" error, it has been because of a modification. So, you may want to try disabling them to see if the error goes away.

it also is placing an error message in the top of the page which reads:

Warning: curl_setopt() [function.curl-setopt]: CURLOPT_FOLLOWLOCATION cannot be activated when in safe_mode or an open_basedir is set in [path]/includes/functions_newpost.php(376) : eval()'d code on line 54

Looks like a plugin issue. Try disabling your modifications/plugins and see if you still have this problem.
Note: To temporarily disable the plugin system, edit config.php and add this line right under <?php
