What does this mean??

Can somebody help me??

We can’t tell you why you are having this problem, but we can tell you how to solve it : install manually.

Simply download yourself the ZIP file (from the link you copied here),
unpack the zip file (Mac: double-click / PC: double-click).

A folder will be automatically created, containing all the files of the plugin.
This is the list of the files.

Simply upload that folder with all its files inside,
inside wp-content/plugins

and then, back to your plugin management page,
activate the plugin.

Can you leave it zipped

No, it has to be decompressed.

When I do that it says there’s a critical file Transfer Error

STOR /public_html/wp-content/plugins/wp-surveys/wp-surveys.pot
Response: 553 Can’t open that file: No such file or directory
Error: Critical file transfer error

I did decompress it too..

How do we solve that Problem?

Two questions :

1. Did you successfully install another plugin in this WordPress ?

2. Is “wp-surveys.pot” the FIRST file supposed to be transferred from that plugin ? (does it fail at the first file ?)
