Hi,
I have created custom web part and added in SharePoint online. Using Setting->WebParts-> Upload file.
But when I am trying to add that web part on page I am getting following error.
The file you imported is not valid. Verify that the file is a Web Part description file (*.webpart or *.dwp) and that it contains well-formed XML.
This is plain web part only some text is added.
Please help.
Thanks,
Pramod
