A specific user profile is no longer visible - Getting this error

Also, noted another error (all happened at the same time). When that user go to his profile and click feed, the page is empty. See attached.

Error file is attached, but here is the last part of the "Error Log":

Last line here:

That file "BxTimelineTemplate.php" is attached here, and line 2938 is below:

                    $aResult['content'] = array_merge($aResult['content'], unserialize($aEvent['content']));

Thanks  for your reply. Here is the answers:

1.Template: Lucid

2.Block in "View Profile" page are as in attached image.

3.visibility is Public.

4.Interesting enough, if you look up this profile from a "standard" or "unauthorized" account, you can see him with no problem. However, if you look him under "admin" account, you get the error (I have two admin accounts and both lead to the same error) but when logged in as a standard account was working OK.

I did reproduce the error this morning and here is the last few lines of the Error log:

BxDolPage::processSeoLink()\n#25 {main}\n  thrown in /var/www/scrubdin.net/modules/boonex/timeline/classes/BxTimelineTemplate.php on line 2938, referer: https://scrubdin.net/member.php

Again, this error happens only after an image was added to a post on his profile (via admin) but visibilty of that post was made to "friends only"...Not sure if that is pertinent or not.

I will send you login information to this site again so you can investigate it directly (appreciate your help on this
