What is the “XMLReader Support Missing” Error?
The “XMLReader Support Missing” error occurs when a PHP application or script attempts to use the XMLReader extension, but the server does not have it installed or enabled. The XMLReader extension is critical for reading and parsing XML data, and its absence may prevent certain features, such as installing templates, from functioning properly.
1
Check for XMLReader Extension Support
Access your server: Log in to your server’s control panel or connect via SSH.
Locate the PHP configuration file: Typically named php.ini.
Edit the configuration file:
Open php.ini using a text editor.
Search for the following line:
;extension=xmlreader
Remove the leading semicolon (;) to uncomment it:
extension=xmlreader
Save changes and exit the editor.
Restart your web server to apply the changes.
2

If the XMLReader extension is not present, install it following instructions for your OS:
Linux (Ubuntu/Debian)
Install on Ubuntu/Debian

3
Verify XMLReader Extension Installation

<?phpphpinfo();?>
Upload the file to your web server’s document root.
Access it in your browser (for example: http://yourdomain.com/phpinfo.php).
Search the page for "xmlreader":
If it appears, the extension is installed and enabled.
