Problem uploading themes and plugins

I seem to have a problem uploading certain themes and plugins with Infinity hosting that I don’t have a problem with other hosts.

My website will get an error from installing the plugin and then my website stops working. I can’t do anything in my wp dashboard and the site is just completely blank. The only way to get it working again is to go to my cpanel and delete the plugin or theme from there. Are other people experiencing this issue and if so is there a solution?

Hard to say from here with this information. You could try to install the plugin manually: Managing Plugins « WordPress Codex
