Warning: array_merge() ERROR

[tscbh]

I read through some of the similar error message from this forum, but I got a very weird problem. Yes, I am using vb 3.0.7 and running php5 under windows. The actually error message was:

Warning: array_merge() [function.array-merge]: Argument #2 is not an array in \online.php on line 285;

When I first view who's online page, there is no error. 60 seconds later when WOL auto refresh I got that error message. Could any one tell me how I can fix this.

I follow the suggestion from Xenon(busy admin) https://vborg.vbsupport.ru/showthrea...28%29+Argument

I put the following section of code on online.php before global.php is called, but I still get the same error message:

// ################### PRE-CACHE TEMPLATES AND DATA ######################
// get special phrase groups
$phrasegroups = array();

// get special data templates from the datastore
$specialtemplates = array();

// pre-cache templates used by all actions
$globaltemplates = array();

// pre-cache templates used by specific actions
$actiontemplates = array();

If anyone have any suggestion, please let me know.
Thanks in advance.
