Symptoms
My script or application is displaying or logging the following error:
Unable to guess the MIME type as no guessers are available (have you enabled the php_fileinfo extension?).
Description
This error is the result of the "fileinfo" PHP extension not being enabled for the PHP version in use by the application.
Workaround
Ensure that the "fileinfo" PHP extension is enabled within WHM's EasyApache module or PHP Selector if in use.
