For the life of me I can't figure out what's wrong. We just launched after migrating from vb4. See AllBuffs.com - Covering CU-Boulder Athletics We are running nginx + pagespeed on Xenforo 1.4.10 using memcached. In the root location of our server we have the favicon we want, but when it gets served it's the default xenforo one. I went and copied over all of the favicon.ico under the root folder with the one we want. We even put favicons.ico in the same folder. Same checksum as favicon.ico. Still nothing. http://www.allbuffs.com/favicon.ico http://www.allbuffs.com/favicons.ico I even modified the PAGE_CONTAINER to add a link to the favicons.ico We then shut off pagespeed and memcached. Stopped nginx and then removed pagespeed's files. Still nothing. We are at a loss for words. We would like for our users to be able to add an icon to their phone based on this.
