Fatal error: Class 'ZipArchive' not found in

For the ZipArchive class to be present, PHP needs to have the zip extension installed.

See this page for installation instructions (both Linux and Windows).

On Amazon ec2 with Ubuntu + nginx + php7, I had the same issues, solved it using:

sudo apt-get install php7.0-zip

On ubuntu desktop, I had to do.

sudo apt-get install php5.6-zip

This installed the library but I still kept on getting the same error, so I had to restart apache using:

sudo service apache2 restart

and it worked.

I'm not seeing it here, so I'd like to add that on Debian/Ubuntu you may need to enable the extension after installing the relative package. So:

sudo apt-get install php-zip
sudo phpenmod zip
sudo service apache2 restart

First of all, The solution for remote server:

If you are using cpanel you may have zip extension installed but not activate. You need to active it. For this case you need to go to cpanel > inside software section > click on PHP version. Then find zip and check it. Now save.

You should see like the image.

Refresh page. The error should disappear.

Note: If you dont found, contact server provider. They will install for you.
