What Is The Main Mistake When Connecting To A Database?
All information about your global WordPress website, such as post data, page-level entries, meta information, plugin settings, login credentials, etc. is stored in your MySQL entry. The only data not created is that there is media content like images and your theme/plugin/core files like index.php, wp-login.php etc. When another person visits your website the PHP code visits the page and requests information from the database, which then displays it to the guest in his browsere.
If for some reason this doesn’t work as expected, save the datastore connection error message as shown below. The whole page is empty because it is not possible to get data to display a particular page because the connection is established and never works properly. Not only does this break your web interface, but it also prevents you from accessing your WordPress dashboard.
However, visitors could not immediately see this error on every interface. It’s like your site will probably be silently served from the cache until it expires. For example, WordPress sites on Allkinsta are cached for 60 minutes by default. So if a niche site is always served from the cache, it might look fine to any visitor.
