What does %s mean?
This is a special character that the browser uses to input your search query. So for example (I know I love examples) let's say you enter "test" the browser will replace %s with 'test". Which would look something similar to this:
Code:
https://xenforo.com/community/search/1/?q=test
Only supported with 2.2?
I will be testing this with other versions shortly. However, I have confirmed that this works with XenForo 2.2.
Should I have the latest version for either Firefox and or Chrome?
It would be best that you ensure you have updated your browser to the latest version to avoid any issues.
