When a change has been made to an item that only appears in the <head> tag (such as the 'Page Title' on the 'Page Settings' tab or the meta-tag fields on the 'General' tab of a brochure page for example), it can be overlooked by the software when comparing changes before uploading the pages.
If this happens, add a word to the 'Text' field of any fragment (any word will do) and upload the site.
Once this has uploaded, check that your changes have taken place then you can delete the extraneous word and upload again to remove it online.
