We are advised by Blogger Buzzer in Blogger Help Group: Something Is Broken I can't post pictures to my blog, that we should clear our browser cache, if any toolbar buttons are missing from the Post Editor screens. Note that there are 3 different techniques for clearing cache, and each has advantages and disadvantages.
According to Pal at Blogger Status, this also affected photo uploads.
This leaves us with open questions.
- What changed in the Post Editor (and Photo Uploads), that we are refreshing?
- Why was no announcement made about what problem was fixed?
