The .htaccess file is a special Apache file that adjusts the way your website behaves. You can edit the existing .htaccess file on your site, or you can create a new text file in any directory and name it .htaccess.
.htaccess files contain lines of codes, which can run quite long.
Sometimes when you edit the .htaccess file in cPanel’s text editor (or in other text editors) the lines wrap and this causes a line break. This line break is a common reason for site errors.
Luckily, this is easy to fix. You can use the Code Editor built into cPanel or an offline editor to format your code.
