Knowledge base: Common Errors (and how to fix them), For WordPress

“Missing or invalid image file” error on Facebook or Pinterest

If you see the error “Missing or invalid image file” in the Activities List or just blank image on your Facebook or Pinterest page,

 

you should check if there is a string “RewriteRule ..(jpg|jpeg|gif|png|bmp)$ – [F,NC]” in the .htaccess file on your cPanel or ftp.

If you found such a string, you should comment-out or delete it.
