Starting two weeks ago, I can't post on my Facebook business page on my computer. (The other administrator can't either.) When I write something, the options to add a picture and schedule the post are missing. The only button is POST, but it doesn't work. I can post on my phone, but it's a pain; and I can't use several functions there. Once a post is scheduled, I can't edit it on the laptop or phone. A Google search doesn't offer any help; neither does Facebook. Help!
