Don't know if this is a sapphire issue or not. I have not tried restoring any backups to test.
My phone, running Sapphire 1.0.0 with Gala S theme will not display Walls, Wall posts, or whatever you want to call it on the full facebook.com site using the stock browser, or Dolphin HD.
The area where the wall and posts should be is completely blank (totally blank white space). If I tab over to say, info, I can see all the users info. tabbing pack to Wall, and all I see is blank again. This doesn't happen on mobile version of the site, or on full site on any of my computers. I have used the full site on my phone since day 1 and I've never seen this problem before now.
I cannot explicitly say this began with my installation of Sapphire. I might have happened after the install.
