check if .net framework is up to date, if not please update first.

https://helpcenter.websitex5.com/post/96403

Also you could check if: you have html option added somewhere ? Try to remove them and see if this works better.

Thank you for the answer,

I have update the framework .net . But error continue to appear.

I see how I could remove html option . 

But in pages property in menu expert there is the file extensionis allways html . it's correct?

I try to change and I will report what happen.

For the moment thank you very much. You give some hope !

Normal pages are html, guestbook, blog (pages with data transfer) are PHP.

When do you have the crash, can you make a prtscrn or give some more information?

During updeting site to ftp server ? Can a connection or firewall interfere ?

Goodmorning,

I have the crash when at step 5 , 

- export site on internet -> done

- export only modified files -> done

- connection -> done (see image file enclosed)

- fatal error occurred (si è verificato un errore imprevisto -> crash

Hello Stefano,

It could depend on an object in the project which is causing this issue or on a file attached in the html&widget object. Try to remove the last objects or files added and then try to export again to see if it works.

Many thanks!
