Facebook old foto

[Thomas]

I post an article on my homepage.
I try to share it via Blog2Social but it shows an old foto.
I change it for all accounts to the new one and get the enclosed message.
But, the message is not true. The article is posted e.g. on my facebook group but with the old foto.

Why ?

[Blog2Social Support]

Hello,

Thank you so much for reaching out and thanks for describing your request.

Would you please be so kind as to answer a few short questions so I could look further into this for you?

On which networks did you face this behavior except for Facebook groups?
Do you have multiple plugins that implement the Open Graph parameters?
Are you currently working with caching and optimization plugins? If yes, which do you use?
Has your server a server-sided caching enabled?

Furthermore, it would be awesome if you could also provide us with the generated/downloaded troubleshooting-tool .txt Log file so we could look further into your environment.

You will find the Troubleshooting-Tool by following this path:
Your WordPress installation -> Blog2Social -> Help & Support -> Troubleshooting-Tool

Make sure to provide us with these details via a private message in the community in order to protect your privacy.

Thank you for your understanding and your effort.
I am looking forward to your reply.

Best regards
Alexander
