What to do:
1) download and import product from attachment.
2) find file /admincp/misc.php and make a backup copy of it
3)in this file find
Code:
WHERE title IN ('bbcode_quote', 'bbcode_php', 'bbcode_code', 'bbcode_html', 'bbcode_video')
replace it with
Code:
WHERE title IN ('bbcode_quote', 'bbcode_php', 'bbcode_code', 'bbcode_html', 'bbcode_video', 'bbcode_highlight')
4) find
Code:
'bbcode_video' =>& $bbcodelist["$tlist[bbcode_video]"],
add afrer
Code:
'bbcode_highlight' =>& $bbcodelist["$tlist[bbcode_highlight]"],
5) find
Code:
'bbcode_video' => intval($tlist['bbcode_video_styleid']),
add after
Code:
'bbcode_highlight' => intval($tlist['bbcode_highlight']),
5) upload this file to ftp
6) go to admin panel and rebuild post cache
Hack usage:
[ syntax = cpp ] or [ highlight = cpp ] or [ code = cpp ] (without spaces)
I also would reccomend to obtain latest version of geshi.
