I have several different styles installed on my XenForo forums and I was wondering if I need to change all of the OG Images, for each theme or do I need to just change it for one? Also, does anyone know how long it can take for Facebook to cache the image to the new one over the old one?
Thanks for any help regarding the matter in advance
You can use a common image or have a different one for each style.
How do I replace the Xenforo Facebook recommend/like logo with my own?
Upload your logo to the server and change the image path in the ACP -> Styles -> Style Properties -> Header and Navigation -> Settings: Facebook Open Graph Logo. Due to caching it can take several weeks for the image to update on the Facebook servers.
