Why Do I Get a "No Input File Specified" Error During Anchor CMS 0.8 Installation?

No Input File Specified: Resolving the Issue for Anchor CMS

When updating to Anchor CMS version 0.8, users may encounter a "No input file specified" error during installation. This problem stems from a mismatch between the CMS's expectations and the server's PHP implementation.

As identified in the provided .htaccess configuration, Anchor CMS expects URLs to be passed as PATH_INFO variables. However, CGI and FastCGI PHP implementations do not support PATH_INFO.

Understanding the Error

This error occurs due to:

• PHP's handling of URLs differs depending on its implementation.
• Anchor CMS relies on PATH_INFO variables for URL parsing.
• CGI and FastCGI implementations, commonly used on shared hosting providers like GoDaddy, do not provide PATH_INFO variables.

Finding Alternate Solutions

There are several options to resolve this:

Option 1: php.ini Configuration Change

• Check if modifying PHP settings via php.ini is allowed on your hosting environment.
• If possible, change the PHP implementation to a mode that supports PATH_INFO variables. However, this option may not be feasible on shared hosting environments.

Option 2: CMS Code Modification

• Add QUERY_STRING to the URI detection array in system/uri.php.

• Change the .htaccess file to pass the URI as QUERY_STRING:

  RewriteRule ^(.*)$ index.php?/ [L]

• This method allows URI parsing but hinders CMS updates without modifying core files.

Alternative Option: Seeking a Better CMS

If the aforementioned solutions are not viable, consider replacing Anchor CMS with a more suitable CMS that is compatible with your hosting environment and offers better support.
