Looks like your variable $featured doesn't have a value (null) when it's supposed to be an array, i.e. your database query did not return any results. Do you actually have a tag "tag" in your database? Or should the argument to the database query have been a variable rather than a string?

It is difficult for me bro. I am a electrical and electronics engineer. It is tough for me to figure this out. That's why I need expert help bro.

Well, I'm trying to help, but like I said, providing more context makes things easier for the people trying to help you.
Anyway, did the config change I mentioned above get rid of that error message? And does the query return the result you expected?

Can you look at this plugin ?
I am trying to show random questions in a widget or in question list with image preview with particular tag. Like when a user open the home page everytime he must see a new funny image which contain a tag as "funny"
do you got my point ?

"No" the config change did not get rid of the error message, or "no" the query did not return the result you expected?
Also, if you're asking me to patch/write the plugin for you, the answer is no. I'm willing to help you fix an issue you have with the code you're writing, but I'm not going to write your code for you.
