Hiya!
I get this error when I open posts or pages that I know for certain this is not true for:
“There is an autosave of this post that is more recent that the version below.”
I ALWAYS save after my edits. Create a PDF. And then download an .XML file!
So I installed a FRESH copy of WP (new database and WP files) and imported my content using Tools Import plugin to see if I could correct this.
And I am still getting the error. SIGH.
Do you have any ideas? Thank you!
