Fixing "Internal Server Error" on Installation Page (Ionos Hosting)

If you encounter an "Internal Server Error" on your installation page while using Ionos hosting, it may be due to a missing directive in your .htaccess file.

Solution

1. Locate and Open Your .htaccess File:

   • This file is usually in the root directory of your website. Ensure your file manager shows hidden files.

2. Edit the .htaccess File:

   • Change the contents from:
     

     RewriteEngine On
     
     RewriteCond %{REQUEST_FILENAME} !-f
     RewriteCond %{REQUEST_FILENAME} !-d
     RewriteRule ^(.*)$ index.php?/$1 [L]

   • To:
     

     RewriteEngine On
     
     RewriteBase /
     
     RewriteCond %{REQUEST_FILENAME} !-f
     RewriteCond %{REQUEST_FILENAME} !-d
     RewriteRule ^(.*)$ index.php?/$1 [L]

3. Save and Upload the File:

   • Save the changes and upload the file back to your server if necessary.

This adjustment adds the RewriteBase / directive, which is essential for the proper functioning of URL rewriting on Ionos hosting. This should resolve the "Internal Server Error" on your installation page.
