ZipArchive class required in order to unzip the file


I uplod a zip extension and I have this error "ZipArchive class required in order to unzip the file"
I use this command line :
yum install php-zip
I have this : .....

vesta | 2.9 kB 00:00
Package php-pecl-zip-1.14.0-1.el6.remi.5.6.x86_64 already installed and latest v ersion
Nothing to do

Then : service httpd restart

But that not works, I have always the same error.
@roland - maybe the zip class is listed in the list of disabled classes in php.ini ?
Eitherway, if mailwizz says the class is missing, it means it's missing, either because it is not enabled (even though is installed) or because it it's classes are disabled.
When Upload the zip I have this success message :"Your extension has been successfully uploaded!"
but I don't found the extension in the list to enable it. I refresh, no thing.
Check in /apps/extensions/ and see if the extension you uploaded is there.
If it's there, make sure the extension dir name is relative with bootstrap extension php.

so if the extension you uploaded has the directory named "my-extension" then make sure the bootstrap php class of the extension is named "MyExtensionExt.php"
@roland - i think best is to contact the developer of the extension and see what the deal is. If the extension is properly created, it will work just fine.
