In the upload folder in your project directory there is a file called versions.xml. It is possible that writing to this xml-file was terminated at the faulty file.

But: Since I haven't had this error myself, I can only guess...

Franz-Josef,

I was hoping I would never get this message!! I looked in the version.xml and right at the end are these 4 lines.

<page id="0" lastmodified="2023-07-29 09:53:02" path="index.html" upath="index.html" construction="False" />
<page id="-9" lastmodified="2023-07-29 09:53:02" path="imsearch.html" upath="imsearch.php" construction="False" />
<page id="3" lastmodified="2023-07-29 09:53:02" path="about-me.html" upath="about-me.html" construction="False" />
<page id="5" lastmodified="2023-07-29 09:53:02" path="contact-nigel.html" upath="contact-nigel.html" construction="False" />

What I find interesting is that the date / time supplied for all three .html files is incorrect as I made small changes to all three pages. The time stamp on the .xml file is correct with the last attempt and marked today. I also checked the server and the .html files match the  date / time stamp to the message.)

If I look in the sitemap.xml, then that too is correct.

There may be two possible solutions

1. Try the following: delete the preview folder in your project directory, then start WebsiteX5 and load your project. The folder will then be rebuilt.
2. Load the last working version from the backup manager.

I found out what it was! Early yesterday I had to make some minor correction on my server for security. I inadvertantly changed the permission on the public_html directory.

If the error message had actually stated what was wrong ( :) ) "can not write to target host" then I would have found my mistake almost immediatly! And there was no indication on the upload / export page that there was an issue.

Very sorry to have wasted your time on my home grown mistake.

Nigel.
