Cannot modify headers - NaturalEnquirer - 2010-08-16

When I try to edit a theme via the themes pages, I get this warning:

Warning: Cannot modify header information - headers already sent by (output started at /home/content/n/a/t/naturalenq/html/flowerkissers/galleries/zp-core/admin-functions.php:78) in /home/content/n/a/t/naturalenq/html/flowerkissers/galleries/zp-core/admin-functions.php on line 3466

Everything else seems fine.

I looked for blank lines and spaces in admin-functions.php but couldn't find any.

Is it safe for me to just replace this file with a fresh copy to see if that fixes the problem?

Anywhere else I should look?

Thank you.

I just tried it on my installation and it happens for me as well. Seems to be a bug related to the XSRF changes.

This is now fixed. The fix will be included in tonight's nightly build.

I'm not sure if this is a bug, or if I am doing something wrong. If I should post this somewhere else, please let me know.

I didn't get this error until after installing version 1.3.1 back on August 16. For a couple weeks the error was restricted to a Cross-Site Forgery Blocked (in the security log it shows as a XSRF Access Blocked). Yesterday, for no apparent reason (it worked fine the day before, and I have no idea what changed), I now get a series of header errors on the back end, followed by an otherwise mostly normal-looking admin page.

If I try to save any edits or changes, I get only errors.

I updated to version 1.3.1.2 today, which had no effect on the errors. I am currently unable to make any changes to my site, or even back up the database.

Thank you for any suggestions.

Something has got corrupted in your PHP session handling. The error message notes a folder that is nt found: (/mnt/w9999/.phpsessions/sess_a26cd5907bceb3e1517e6580e5a8fcaa, O_RDWR Since this folder is not part of Zenphoto and I suspect it is not within the Zenphoto installation either I do not know what would have caused it not to be present. Anyway, Zenphoto Admin has always required sessions, so somehow the folder has been deleted or there is a problem with sessios on your server.

Best to ask your provider about this.

This information will possibly be useful to them.

Thanks for the info. I'll go submit a help ticket with my host provider. I hadn't realized it might be a bigger problem with the server or service.
