If you guys use "Downml - Download Media Liblary plugin"
You need to replace some codes using cpanel coz its outdate plugin. 

1. Go to wp-content -&gt; plugins -&gt; downml 
2. And find this "downml_settings_page.php" 
3. at the line 26 of it's code where you can find this entry:

f($zip-&gt;open($destination,$overwrite ? ZIPARCHIVE::OVERWRITE : ZIPARCHIVE::CREATE) !== true) {

4. Replace it with this codes

if($zip-&gt;open($destination, ZIPARCHIVE::CREATE) !== true) {

5. Save changes and reload wordpress dashboard, its should work now.

I've tried it before i leave a coment coz i need backup iamges from my website.
