I recently did a resintall of my website and used the latest XAMPPlite that comes with PHP5.
When i load a Wiki document i get the following at the top of the page:
Warning: array_merge() [function.array-merge]: Argument #2 is not an array...
A quick review of sourceforge revealed:
BUG#5740 PHP5 and Erfurtwiki - error with array_merge (http://erfurtwiki.sourceforge.net/examples/plainwhite.php?page=OldBugs)
Is there a fix planned?
I think Martin added/updated something to the code that another Moodler asked about approximately a week ago. You may want to contact him about it to see just where Moodle and PHP5 stands right now.
