Issue ARequirements Checks
How to resolve requirement checks that show up on step 1 of the build process?
Before you create a new package a requirements check will show you the status of your system.The following are system checks that are performed before package creation can take place.
PHP Support
- Duplicator requires PHP 5.3.8+ or higher. Contact your host to upgrade to a stable secure version of a PHP Release
- To create a zip file the plugin requires ZipArchive extension -OR-shell_exec for PHP with zip support enabled. Contact your hostto enable. Alternatively you can also use the DupArchive format found on the Duplicator > Settings > Packages Tab > Archive Engine.
Permissions
- Paths that are listed in this section should have permissions of 755 for directories and 644 for files. On some hosts the permission set requires 777.Setting items to 777 is a security issue and should only be set temporarily. Please avoid any hosting company that requires this kind of setup.
- Also be sure to check the Owner/Group settings and validate they are correct and match other successful directories/files that are accessible.For more details contact your host or visit their help pages for more information on how they implement permissions and group settings.
Server Support
- WEB SERVER:The Duplicator currently works with these web servers: Apache, LiteSpeed, Nginx, Lighttpd, IIS, WebServerX. However the best success we have seen with Apache
- DATABASE SERVER:In order to complete an install the mysqli extension for PHP is required. If you are on a hosted server please contact your host and requestthat mysqli extension be enabled. For more information visit: http://php.net/manual/en/mysqli.installation.php
