Your new host may have a server-side security script, like mod_security blocking PHP’s ability to copy files. You may want to contact them about that. For now, you should be able to install plugins manually:

hmm … where can i see if the server has that kind of script ?
The problem most likely has to do with how your new server is configured. If no one here has a workable solution for you, contact the host’s support and see if they have one.
If you can’t get auto-install working, do it the old fashioned way. First download and unzip the plugin. Put the plugin folder extracted from the zip file on your desktop. If you have an FTP program, upload the extracted folder to /wp-content/plugins. If you don’t have an FTP program, go into your website host control panel and use its file manager to upload the folder from your desktop into /wp-content/plugins.
With either method, after the folder is on the server go into WP’s dashboard nav Plugins option and activate the newly uploaded plugin.
i know that .. but i want the auto-install 🙁

You’ll have to contact your hosting provider about that.
