What potential issues can arise from using php_flag engine off indexignore in PHP?

Using php_flag engine off indexignore in PHP can potentially disable the PHP engine, causing PHP code to not be executed properly. This can result in the PHP code being displayed as plain text on the browser instead of being processed. To solve this issue, you can remove or comment out the php_flag engine off indexignore directive in your .htaccess file.

# Remove or comment out the php_flag engine off indexignore directive in .htaccess file
