 * Can someone please help with this?
    Warning: Cannot modify header information–
   headers already sent by (output started at /home/.yalaheater/mindgapo/mindgap.
   org/wp-content/themes/rin/index.php:2) in /home/.yalaheater/mindgapo/mindgap.
   org/wp-includes/pluggable-functions.php on line 177 It occured after updating
   and eventhough I already tried a few things I could not solve it? Has it eventually
   to do with the Rin Theme? UPDATE: I checked the Rin index but could not solve
   the problem by the blank space problem as mentioned in FAQ. If I try to view 
   the site from inside the admin panel I get errors for the admin.php also concerning
   the header. Would be really helpful someone could suggest something. Thank you.

 * I’m having a very similar problem. These two show up:
 * Warning: gethostbyaddr(): Address is not a valid IPv4 or IPv6 address in…
 * Warning: Cannot modify header information – headers already sent by…
 * Is this caused by a new plugin?

 * mo2this, I don’t if this helps, but I had a similar problem (though with another
   file)
    It appeared that file got corrupted on my server and was generating this
   type of error. I copied across the original version of the file from my pc to
   the server and it solved the issue.
