PHP4 to PHP5

[ravenfire]

I am going to change from PHP4 to PHP5. Are there any known issues, or settings on vBulletin I will have to change after making this move?

Thanks

There shouldn't be, vBulletin works fine on PHP5

vbulletin will be fine. However, some of the modifications that people install have been found to have some problems - namely an error with array_merge. There is an article in the Articles forum over at vb.org on how to fix this. I would check out the modification threads for mods you have installed and see if anyone mentions this problem and if there is a fix and then fix it prior to the upgrade.
