If you’ve ever seen the “Error establishing a database connection” message on your WordPress site, you know how unpleasant it is. The site stops working, visitors see nothing but a white screen with that phrase, and anxiety gradually rises. In reality, this is one of the most common WordPress issues, and it can be fixed without panic or hiring outside specialists.
Error 404 Not Found is one of the most common problems WordPress site owners face. This message appears when the server cannot find the page requested by the user. The reason could be due to link settings, deleted content, or even the theme of the site.
If not handled properly, the error can affect visitor behavior and search rankings. In this article, briefly and to the point, we will tell you why a 404 error appears in WordPress and how to fix it.
The .htaccess file is a configuration file used on Apache web servers to manage website settings without access to the server’s main configuration. With it, you can enable redirects, restrict access, configure SEO-friendly URLs, set up caching, and much more—directly from the root of your site or any of its directories.
Many CMSs automatically create this file on installation or include a sample in the distribution.
If you're working with hosting, especially on Apache, it's important to know what the default .htaccess looks like for different CMSs. This helps you:
Check that everything is correct after installation;
Restore the file if it was accidentally deleted;
Understand what rules the system uses “out of the box”.
