[Forum] Linear display issue

[qpurser]

I am running 4.1.5 on a test server and worked well so far however when I go into a thread the whole layout is suddenly messed up.. See attachment

Above the layout I get following message: Warning: implode() [function.implode]: Invalid arguments passed in [path]/showthread.php on line 938

Looking into that line:

// '0' inside parenthesis in unlikely case we have no ids for this page
    // (this could happen if the replycount is wrong in the db)
    $postids = "post.postid IN (0" . implode(',', $ids) . ")";

When I switch to hybrid or threaded mode I have no issues

Any help would be appreciated

Try a default style.

Try a default style.

Thanks for trying to help.
Changed to the default vB4 style but still the issue. Well kinda the same.
Same error message above the forum but the thread it self doesn't show up at all. I can go into the thread but no content is displayed until I go into hybrid or threaded mode

Bump for some help

Have you tried disabling all products and plugins?

All plugins disabled and still the same issue.
Linear mode screws up the layout or doesn't show the thread content
Hybrid and threaded mode just work fine
