Getting errors to Log, Sleep, Parse XML keywords

I am getting error for few keywords in my script, It was working fine till y’day and its throwing error all of a sudden. Not sure what went wrong.
Attached screenshot
Code given below: Note, Input Text is not throwing error.
*** Settings ***
Library SeleniumLibrary

*** Variables ***
${test} test

*** Keywords ***

Log  helloo  
Sleep   2s
Input Text   ${test}   test

How about telling us what IDE is that?

What changed from on day to the other?

If you remove the empty line after the keyword name LogTry, does it fix it?
