Fatal Error: Class 'finfo' not found

I’m having the same problem. I’ve tried to install it from a zip at the original source and even my own host, and it’s not working.

Check first if your hosting is running PHP5.3 since finfo() is a PHP 5.3 function : https://php.net/manual/en/function.finfo-file.php

If you are running < 5.3, check with your hosting provider if they can do an upgrade. There is also the possibility that you need to modify your .htaccess file in order to force .php files being parsed using 5.3.

Include these lines in your .htaccess:

# Use PHP 5.3
AddType application/x-httpd-php53 .php

If you have no idea what .htaccess is (which is totally fine, nothing to be ashamed of), check out this site: https://www.htaccess-guide.com/ (or you can google it)

I had the same problem, so I added to the .htaccess

# Use PHP 5.3
AddType application/x-httpd-php53 .php

The result was that every php in the admin area tried to be downloaded instead of opening as a webpage (I couldn’t get to the add theme/plugin page)

My server is running PHP 5.3.27

Any other suggestions?
