There could be several reasons why you are unable to see a Facebook friend's profile even if you are not blocked. Here are some possibilities:
Privacy Settings: Your friend might have adjusted their privacy settings to limit what information and posts can be seen by certain groups of people, including friends. They might have restricted access to their profile for friends only, or they might have added you to a specific list with limited permissions.
Unfriended or Removed from Friend List: It's possible that your friend has unfriended you or removed you from their friend list. In this case, you won't be able to see their profile anymore until you become friends again.
Deactivated or Deleted Account: If your friend has deactivated or deleted their Facebook account, you won't be able to view their profile until they reactivate or recreate it.
Technical Glitches: Sometimes, Facebook experiences technical issues that can temporarily affect visibility of profiles. In such cases, the problem usually resolves itself after a while.
Restricted Profile: If your friend has added you to their restricted list, they might have limited what you can see on their profile. This list allows them to share posts with friends except those on the restricted list.
Blocking: Although you mentioned that you are not blocked, it's still worth considering this option, as blocking would be a straightforward reason for not being able to see someone's profile.
Name Change or Profile Customization: If your friend has changed their profile name or customized their profile URL, it's possible that you might not recognize their profile when searching for them.
To determine the specific reason why you can't see your friend's profile, you can try the following steps:
Search for Their Profile: Double-check that you are using the correct spelling of their name or profile URL when searching.
Mutual Friends: If you have mutual friends, you can ask one of them to confirm if they can still see your friend's profile.
Ask Your Friend: If you have other means of communication with your friend outside of Facebook, you can ask them directly if there are any privacy settings or changes they have made that could be affecting your ability to view their profile.
Remember, people have the right to control their privacy and decide who can see their content on social media platforms. If your friend has chosen to limit your access to their profile, it's essential to respect their decision.
