Worked OK for me on php 5.4 ?
Anyway it does not appear to work on php 7.x I have not yet had chance to look at a fix for it although in theory it does not (appear) to be a difficult thing to sort out.
Code:
Call to undefined function split() in ....\includes\functions_autotagger.php on line 148
Only in php7 , php5.6 perfectly fine

. Confirmed by switching back to 5x without any issues and it works.
Trace:
Code:
#1 : vbstop() called in ....\includes\class_core.php on line 3834
#2 : vbulletin_exception_handler() called in on line
Var Type: [ NULL ]
Var Data: null
Something here tells me that likely a "require" or "require once" might be all that is needed as I cannot quite see why said function is awol in a different php version, unless its one of the &= vs = things.
I've not looked into this just yet but if anyone has any clues would be appreciated to point me in the right direction!
