[Plugin: WPBook] Cannot modify header information – headers already sent by

What version of wpbook are you running?

Looks to me like you have “enable wpbook to create a debug file” enabled, but permissions on the wpbook directly don’t allow the file to be created or written to.

WPBook version – 2.1.4.
I disable creation debug file, but problem is still here.

Can you add:

if($wpbookOptions['wpbook_enable_debug'] == "true")
    define ('DEBUG',true);
  else
    define ('DEBUG',false);

at line 18 of publish_to_facebook.php?

It may be that wpbook is finding a constant DEBUG already defined, which is what is checking for -some other plugin may have defined that already.

The other option would be to just add a:

define ('DEBUG',false);

without the conditional statement, which will make it always not create the debug file

Thanks!

This problem has been resolved after creation log file and change rights for it.

But I have another problem:
when I try publish some message to my group page error occur

Caught exception in publish to page Invalid OAuth access token. Error code: 0

I check all rights in FB – its ok.
this is from log file:

What is problem?
Thank you.

When you say you “check all rights in FB – its ok” – what does your “check permissions” page say, exactly?

From the debug file above there’s clearly no “Page access token” being stored.

Go to WordPress->Settings->WPBook, look in the Stream/Wall options, and click “Check permissions.”

That should load a page in FB showing you your FB profile ID, permission settings, and whether or not an access token has been stored for you and for your page. Copy and paste that info here so I can review it

that`s it

This page is where you can check and grant extended permissions, which enable WPBook to publish to your personal wall and/or to the walls of fan pages.

Your userid is 823473569

You will need to enter that number into the WPBook settings page on your WordPress install.

This user_id has granted these permissions:

* offline_access – yes
* read_stream – yes
* publish_stream – yes
* manage_pages – yes

This user has set an access_token for the application to use.

You’ve indicated you wish to publish to this page: 172942786091565

WPBook stored an access_token for use as as well.

To correct any of these, Grant or re-grant permissions for your userid. (This is required if you intend to publish to your personal wall OR any fan pages.)

Note at the bottom where it says:

You’ve indicated you wish to publish to this page: 172942786091565

WPBook stored an access_token for use as as well.

It’s subtle, I know (fixing that in a later release) but that last sentence doesn’t say “WPBook *HAS* stored an access token”

In other words, no access token has been stored for that page.

Looking at the ID in Facebook graph, I can see that this is a GROUP not a page – that may be the issue here, as I haven’t accounted for GROUPs in the new Facebook API (since 2.1 of WPBook).

Groups will need to be treated differently – part of the new Facebook API is that each kind of object has a different mechanism for posting to it.

So, for now, I think that means that posting to a group’s wall is unsupported until I add logic for that.

I see!

Many thanks for you.

I try to resolve this problem in FB group account.

So, thank you and I`m waiting for update.

Dimitry.

@pla.mailbox 2.2.1 supports publishing to group walls – please let us know how it works for you

Thank you!
I check it ??
