when upgrading from XF1.0.0 to XF 1.0.4, my custom logo-image (the one which shows at "Recent Activity" / "Facebook Recommendations" within the sidebar changed to the default XenForo-image.
Where do I change this back so that my custom-logo appears again?
How and where to set the image-path to my custom-image so that this will not change back to the default XF-image when doing an upgrade again?
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.
