any ideas what might be causing it?

nope sorry, no idea...

is it work on 2.3.0?

i haven't tested it, but as it uses it's own files and the tables thread/posts were not changed it should :)

xm... but it`s look like u not fix that thing with permissions yet... :(

no i didn't get time to work on this hack anymore...

i hope i can fix the problem itself while porting the hack over to vb3

will u porting it on vb3?!

i will, that's 99% sure, but i don't know when i'll find the time.
i think it wouldn't be that easy because of the renamed functionnames aso..

i think i have to recode it nearly from zero

I have installed your Archive hack.
I'm using 2.2.7 VB & PHP 4.3.4 with Apache
Here is the error:
Parse error: parse error, unexpected '=' in C:\Network\Apache2\htdocs\forum\showarchiv.php on line 260

What did I do wrong??

it seems the zip file contained one buggy file.

download it again and replace the showarchive.php with the one including in the zip now :)
