I download 3.0 source code and run it in my computer.
When I upload existing file or open demo.docx, it renders it and enter to edit mode successfully.
I modify the docx such as entering some words and then close the web browser.
and then I reopen the browser and link to that docx file.
But it shows "Version changed" error message.
and i can't edit the docx file any more.
Even though I reload it several times, and tried other files, the prog shows the same error.
If u solve this problem, it is very thankful.
