Updated to 3.0.3 now my site edits don't show up

I have been developing my WordPress site in MAMP using on my Mac. I’ve been uploading to a remote server/shared hosting account to occasionally test the site online. Things were going great until this week.

My most recent edits to my MAMP/localhost site are not showing up after uploading them to the remote site. Specifically, my most recent edits to my customized CSS file, my recent changes to some of my WordPress pages via the content editor and most recent customizations to my widgets are not visible.

I have deleted all the WordPress files on the remote server and dropped all the data in my WordPress database files and re-uploaded all the WordPress files and re-imported with current database file. Done this several times. I have made sure that the site is pointing to the correct address in the wp_options table by making sure that “siteurl” and “home” are set to the correct remote domain url.

When logged into MAMP everything looks as it should. But when viewing my remote site these recent edits are not showing up.

I see something in WordPress news about v3.0.3

WordPress 3.0.3 is available and is a security update for all previous WordPress versions.

This release fixes issues in the remote publishing interface, which under certain circumstances allowed Author- and Contributor-level users to improperly edit, publish, or delete posts.

These issues only affect sites that have remote publishing enabled.

Remote publishing is disabled by default, but you may have enabled it to use a remote publishing client such as one of the WordPress mobile apps. You can check these settings on the “Settings → Writing” screen.

But I don’t understand what to do in my settings>writing screen or know if this will help. Any ideas? Thanks.
