I get the following exception in my system.This system worked properly. But suddenly got and exception. I tried doing debugging. But I couldn't find the anything. This is about a profile picture upload. I did some removing of code and I got the error. But then I again add those codes but nothing happen. I tried some solutions in the internet but didn't work. I'm new to this work so please help me if you can. I tried removing some of the codes then I got an error saying invalid operation.
How can I fix this?
I tried to debug and find where the problem occurs, unfortunately I couldn't find where it is.But I guess the problem should be in these codes. These two codes created the exception
