Hello bro,
To properly configure SSL in your wordpress install, You first need to go to Wordpress admin settings > General > and edit wordpress address url and site address url to https
then install better search and replace plugin from here:
https://wordpress.org/plugins/better-search-replace/
and in the Search for field, enter this "
http://codeair.in"
and in Replace with field, enter this "
https://codeair.in"
From select tables, select all tables using Cntrl + A
Case insensitive field should be unchecked
Replace GUIDs should be unchecked
Run as dry run should be enabled. After scanning, it will give u results of all the non ssl links, now re-run the same steps of this plugin but this time uncheck Run as dry run option.
Now all your internal site links will be https in database too.
Now, either use .htaccess and add https headers to it, or simply use plugin for automated operation.
Plugin i recommend is "Really simple SSL" or its pro version (You can find it in this forum)
This will definitely solve the issue. If not, let me know and I will help you for sure.
