I have just updated several pages on my site, and exported them, and uploaded my export to my server.
However the “new” page did not appear when I went online, and when I looked back the exported version on my computer, it says that these pages were created yesterday 11:30. No they weren’t; they were created and saved today at 9:30.
Why aren’t these pages showing up as pages created today in the export.
Did you definitely save the project before exporting? Also, if you exported to the same location did you choose the option to replace all? As a test I would try exporting to another location and see what is included.
