I try also control+priview nothing. Change the local server to 128.0.0.11:8080/index.html also I try port 8081 nothing 

Hello.Try to run the program as administrator.

If running as Administrator works - that's great!!

If it doesn't . . . . .

Temporarily disable or remove AVG and Malwarebytes (might as well hit Spybot as well), these programs have been known to block WX5 in the past. If this turns out to be the case, exceptions can be put in place.

(If you haven't exported the project/s recently, please do so. IWZIP is the only reliable form of backup in a catastrophe)

Although i run the program as administrator, it does not show the contents in "page creation". Does this bug repeat frequently?

i think... ...the same issue:

Many people including me can not speak Italian. However link of English topic does not contain solution. Issue proceeds the same. Anybody knows solution?

Grigorios, please sign in with the credentials you used to purchase v2019.3

Serkan, I used Google Translate add-on for firefox so I could read the posts, sadly no-one has the absolute solution.

If you have the time I would like to suggest you uninstall WX5 and use Windows Explorer to remove the current profile

c:\users\yourname\appdata\local\incomedia\website x5 pro (? - sorry, I think this is correct but I do not allow WX5 to load new versions in the same folder, so mine doesn't look like this)

Once deleted, download a clean install from your profile and re-install.

Please advise if this resolves the problem (or otherwise)

Thanks for the advice. For the time I run the program as administrator. I will use it and I will post the results.
