Switch Windows to Linux, Cannot Modify Header Information Errors

[browneandrae]

Yesterday we made a switch from Windows to Linux through GoDaddy and I believe that error messages appearing on the sites wp-login.php are associated with it. There are four lines:

 

 

Warning: Cannot modify header information - headers already sent by (output started at /home/content/88/9177388/html/datacentersummiteast-rtp/wp-content/themes/news/functions.php:1) in /home/content/88/9177388/html/datacentersummiteast-rtp/wp-login.php on line 349

 

Warning: Cannot modify header information - headers already sent by (output started at /home/content/88/9177388/html/datacentersummiteast-rtp/wp-content/themes/news/functions.php:1) in /home/content/88/9177388/html/datacentersummiteast-rtp/wp-login.php on line 361

Warning: Unknown: Failed to write session data (files). Please verify that the current setting of session.save_path is correct () in Unknown on line 0

 

I know that it might have something to do with PHP not being able to write to the /tmp directory or a missing/tmp directory. I am not sure how to fix the lines in the wp-login and function php files and I am not sure about any other way to resolve the issue.

Two different errors.

1. What's at the very beginning of the themes/news/functions.php file? There's something that PHP is outputting - perhaps a UTF-8 bom, or perhaps whitespace before the <?php tag.

2. Does that tmp folder exist on the new machine? If not then create it and set 0777 permissions on it.

Here is a copy of the php

 

GoDaddy hosts the website, how do we figure out where to place the tmp file if we have a host provider that did the switch to linux for us. We do have file transfer protocol capabilities. I just don't know the proper location for the tmp file.

Open the functions.php file with Notepad++ and then go to View > Show Symbol > Show All Characters. Does anything appear before <?php?

[browneandrae]

After showing all characters using Notepad++, I do not see any spaces before <?php just cr lf in boxes after it.

[scootstah]

I think what you are experiencing is a Byte Order Mark or BOM.

 

What character encoding does the file use?

The issue has been fixed. Thank you
