My latest posting doesn't show up when I use Firefox version 1.0.4. It shows up on safari and on Micrsoft Explorer. I tried to post it again, but it didn't help.
When that happens, wait until the page is completely finished loading and then do a forced reload of the page (Control-F5). Jeremiah is right abought clearing the cache. The reload bypasses the cache temporarily. But in general, after making significant changes to your template or posting entries, clearing the current cache is a good idea.
So glad I found this group, I'm moving my posts from my Bravejournal blog to Blogger the hard way (one at a time) and when I republished, half of Dec 2005 didn't show up :( For the life of me I couldn't figure out why. Found the link here from Blogger, read the responses on this thread and now all my posts show up. I never even thought of doing something with the cache. Thanks guys :)
