I've had this problem for a while now; I hoped that it would go away when I moved to my new host but it hasn't. Whenever I try to install or update a plugin or theme, or even update Wordpress, the page will simply say
downloading install package ... but that is the only line that ever appears. If I leave it for a sufficient time the operation will complete successfully but Wordpress will only ever display the first step.
I'm running the latest version of Wordpress and everything is up to date. Does any one know why this is happening and how to resolve it?
Thanks in advance
