I have a site hosted on 1&1 Ionos hosting. Purchased an SSL for the site from 1&1 Ionos as well. So let's say https://www.business.com/ is what I have. Then I have another another site say http://www.mycompany.com/ hosted at the same place - still waiting for my business SSL to be approved hence the http.
So I exported the database from business.com using plugin WP Migrated DB - setting the new URL and actual filepath.
Then I imported the database into a new database for my staging environment to be hosted at http://www.mycompany.com/clients/business.
I copied ALL the wordpress files for the site http://www.business.com/ into http://www.mycompany.com/clients/business exactly except I changed wp_config.php file to reflect the new database details. i.e username, database, location and password.
So I expected http://www.mycompany.com/clients/business to be a complete replica of the original https://www.business.com/. But when I browse to http://www.mycompany.com/clients/business I get the following error:
This site can’t provide a secure connection mycompany.com sent an invalid response. Try running Windows Network Diagnostics. ERR_SSL_PROTOCOL_ERROR
I can't even login to the admin panel of http://www.mycompany.com/clients/business/wp-admin
Is what I tried even possible and if it is please tell me what I did wrong and how to fix it. I'd like to create a staging environment to test new themes and plugins before implementing on live environment. Critical to my original site is the aMember plugin which manages all the membership registration info. I've deleted the Really Simple SSL plugin folder from WP-Content/Plugins folder but the error remains.
Thanks in advance for any and all help and advice!
Step 1: Check your .htaccess for rules enforcing https
Step 2: Did you replace all links in the database? If not, you must search and replace all links from https://www.business.com/ to http://www.mycompany.com/ You can use a tool from: https://interconnectit.com/products/search-and-replace-for-wordpress-databases/comment-page-4/
Or just use command line wpcli (wp search-replace https://www.business.com http://www.mycompany.com
Step 3: Open the new 'http://www.mycompany.com/' in a incognito tab. Browser caching might still redirect you to https.
