Been getting these random white screen errors visiting posts on my website.

An exception occurred: [TypeError] Argument 1 passed to XF\Entity\User::canStartConversationWith() must be an instance of XF\Entity\User, null given in src\XF\Entity\User.php on line 830

This appears to be a bug with a template modification (calling canStartConversationWith without checking that it actually has a user).

It's odd it seems to be a specific forums thread/Post

I am wondering maybe there is something damaged with that Thread?

According to this Google Cache:

The last post in that thread is a Guest. That ties in exactly with what Mike suggested about calling that function without having a valid user record.

So if the code is something like:

<xf:if is="$xf.visitor.canStartConversationWith($user)">

It would need to be changed to something like:

<xf:if is="$user.user_id AND $xf.visitor.canStartConversationWith($user)">

 

[CoZmicShReddeR]

I really wasn't disagreeing with him I just don't exactly know what you guys are talking about all the time...

So I am still guessing from my limited knowledge with this is that the thread has no one set as the author as to referring the $user.user_id so I would have to possibly add a user through the database as the author?

 

[Chris D]

To simplify it, it all boils down to who or what added that code. It's not XF code so it has either been added by you or your style or an add-on. Once you've tracked that down, it's best to either ask whoever added the code, or if it was yourself, post the code that you added in a new thread in the Styling & customizations forum and we'll go from there.

 

[CoZmicShReddeR]

Yeah, thankfully someone noticed the code work from an add-on all is well!
