It’s possible that the plugin exceeds the maximum file size. Please try installing it manually.

@nathji please use ftp file transfer program to upload plugin. Maximum file upload limit is 10MB so split plugin into parts. But mostly plugins are from 1 MB to 7MB that are commonly used. Which plugin are you trying to install??
