If you have used a Serif product to design your website, then it is very likely that you will not be able to upload to your webspace correctly.
Instead follow the guidelines below.
In Serif, select, File > Publish to > File Folder, then choose to save All Files to your preferred destination (we suggest initially a new empty folder).
Next, using FileZilla (downloadable from our Help page), connect to your web server account, and your new folder you created above.
Now, upload all your files from within this folder on your pc, to the root folder on your web server account.
Your web files are now uploaded.
