I’m attempting to set up cross posting to my FB page (not profile) I’m also receiving error message:
Caught exception in publish to page (#200) This API call requires a valid app_id. Error code: 0
I checked the page settings as shown in comparison to your example from a previous resolved post. No access token info appears after:
<You’ve indicated you wish to publish to this page: XXXXXXXX>
There is one after the profile info, but not the page number.
I have regenerated tokens several times but one never appears for the FB page I wish to connect my blog to. How can I fix this?
