i upload my wordpress theme it all good but cannot show the post 404

i install my wordpress manually by uploading my own theme into the server , then after all finish the website is good . But then i try to post an article, i cant open the article it says 404 error . What should i do to fix this ?

A couple of things to try:

Go to the file manager of the site in Cyberpanel and click 'Fix permissions".

In WordPress dashboard go to permalink settings. Don’t change any settings but just click to save them.

Hopefully one of those should fix it.

/usr/local/lsws/bin/lswsctrl restart
