Is your token expiring frequently?
Is your access token for Instagram or Facebook showing invalid after a short period of time? We are seeing this happen for users with security plugins installed (like Sucuri Security for example) or any plugin that might be rotating the WordPress Salts & Keys. This will cause the social media access token to be invalidated. The reason is because we are using the Salts & Keys to encrypt the Instagram, Facebook Tokens and Feeds.
If there is a setting to rotate your security keys, you will need to disable this setting. Then the token authorization should not be invalidated. If not, you will need to gain a new access token. We are looking into a possible work around but for now that is our suggestion when using Feed Them Social for an Instagram or Facebook Feed.
