Do you use a custom made template and is it contructed from standard x5 files?

Make a copy, import the copy change to a standard template. Then import if this works then correct your template. This is offcource a workaround.

Hope this helps.

How can I import the projects WebX5 version 9 to version 10 WebX5.
When I try to open the project he accuses the same "error: xml document (237.17)," how can I do to not lose all my projects?

There I was fortunate that Tino and I believe that is not something that is solved by luck

Hello Felipe,

you need to export the projects in Version 9 as IWZIP and then you need to import the projects in Version 10. It's not working to change the project folder in V10 by adding the one used in Version 9.

Many thanks!

 And what if Version 9 doesn't work anymore?
