I am working with my new website. I got SSL certificates file from Digicert SSL provider . I installed SSL as instructed . But my WordPress pages still get Insecure page error while other html and non-WordPress PHP pages works Okay. I am not sure what did i do wrong. my website is
https://www.devbhusal.com/ shows insecure page error.
https://www.devbhusal.com/readme.html works fine.
https://www.devbhusal.com/test.php works fine.
If SSL installed successfully with domain and still site is not secure then please check if internal link used only http:// if yes then convert to https:// and still you not able to find then you can use https://wordpress.org/plugins/really-simple-ssl/ plugin.
