XF 2.0 ErrorException: Template error: Cannot call method isMemberOf on a non-object (NULL)

[Mattia Del Franco]

Hi,
this error is spamming my Xenforo error log, it generates likely everytime someone loads a post page.

How I could stop/fix this?

Did you follow this guide by @Chris D https://xenforo.com/community/threa...-by-premium-members.49986/page-2#post-1255631 ?

It is buggy, see the correction you need to make here; https://xenforo.com/community/threads/highlight-threads-made-by-premium-members.49986/post-1268582

Nope, but I have a similar code in messagge_macros template:

                <xf:if is="{{$user.isMemberOf(152)}}">
                    <span class="userlvl lvl3" data-xf-init="tooltip" title="Utente di Livello 3"><i class="fa fa-star"></i></span>
                <xf:elseif is="{{$user.isMemberOf(153)}}" />
                    <span class="userlvl lvl2" data-xf-init="tooltip" title="Utente di Livello 2"><i class="fa fa-star"></i></span>
                <xf:elseif is="{{$user.isMemberOf(2)}}" />
                    <span class="userlvl lvl1" data-xf-init="tooltip" title="Utente di Livello 1"><i class="fa fa-star"></i></span>
                </xf:if>

Here's another code in PAGE_CONTAINER template:

                <xf:if is="in_array({$forum.node_id}, [545, 785, 1894, 1042, 1092, 79, 56, 35, 40, 37, 1972, 268, 1975, 1979, 545, 307, 681, 731, 679])">
                    <xf:widget key="gameparade" />
                </xf:if>

And this in post_macros template:

                            <xf:if is="$post.user_id == $thread.user_id">
                            <span class="threadauthor">Autore del topic</span>
                            </xf:if>

                <xf:if is="$user is not empty">
                    <xf:if is="$user.isMemberOf(152)">
                        <span class="userlvl lvl3" data-xf-init="tooltip" title="Utente di Livello 3"><i class="fa fa-star"></i></span>
                    <xf:elseif is="$user.isMemberOf(153)" />
                        <span class="userlvl lvl2" data-xf-init="tooltip" title="Utente di Livello 2"><i class="fa fa-star"></i></span>
                    <xf:elseif is="$user.isMemberOf(2)" />
                        <span class="userlvl lvl1" data-xf-init="tooltip" title="Utente di Livello 1"><i class="fa fa-star"></i></span>
                    </xf:if>
                </xf:if>

Perhaps that will fix it.

I think just adding:

<xf:if is="$user">
// your code here
</xf:if>

similarly to what Fillip suggested should do the trick. I think it happens also if there are deleted users, since they're no more "users" for Xenforo, it'd log server errors, so this way you should prevent it.
