MyBB Community Forums

When I copy and paste the link into Eg. Facebook the description it gives is the default "Webmaster, Graphic design Forum..." or something - I changed in the template and reinstalled it and re-used it after forcing it on users. It still says it though how can i change the description...

Also it comes up with a horrible logo or something grey how can I change this - Try it for yourself on facebook .

Have you set meta tags ie og:title and og:description on that page ?
Try doing that and check using developer tool on facebook

Thanks

Also, I don't know how long Facebook caches those values.
