Question
I can't find questions I asked in Stack Overflow, and some questions are unaccepted but I can't find them. Where can I find my unaccepted questions and asked questions?
Solution
If the question does not appear in the Questions tab in your profile, it means it got deleted. Only a moderator can still see it in your profile and only moderators or users with more than 10,000 reputation can view such question.
You can ask a moderator (here in Meta or by flagging one of your own existing posts) to have a look telling what to look for and he can explain why it got deleted.
As for "questions are unaccepted" I assume you mean questions you still did not choose accepted answer? In such case, it's possible to distinguish them in the Questions tab in your profile by the text color - only if the color of the text is yellow it means you accepted an answer otherwise you didn't:
When you have many questions or want only the questions without accepted answer in one list you can use advanced search for this, just add "hasaccepted:0" to the search query. Here is the full search link: https://stackoverflow.com/search?q=user%3A1084732+hasaccepted%3A0
OTHER TIPS
The 'questions' menu item, between 'answers' and 'tags.'
