UBB.threads PHP Forum Software Community Forums UBB.threads 6 Version 6 Support array_keys(): The first argument should be an array

Hey guys,

I've converted an OLD, OLD (v4.4) wwwthreads message board to 6.4.4. All of the posts, etc, and features work, except I get the error below, only on imported (imported via alter tables) threads that have zero replies. New posts with 0 replies do not get the warning. This also only happens when a user is looking at the post in threaded mode. Any hints/tips?

(obscured the path purposefully)

Warning: array_keys(): The first argument should be an array in /path/to/boards/showthreaded.php on line 97

The line is:
$parentkeys = array_keys($tree[$currentkey]);

Smashed this bug myself - this might be a forgotten piece of code since it wasn't expected to affect anything...

There are two calls to show_replies() in showthreaded.php

One call has this guard:
if (isset($tree[$PNumber]['children'])) {

The other has no guard, so I added the following:
if (isset($tree[$current]['children'])) {

and it seems to be working correctly so far.
