Darn it lol...
So I sat there for about half an hour, searching through forumdisplay.php, saying to myself "Where the hell is the little bugger"...
I had recently read an article on PHP.net about common errors with PHP, and discovered a gentleman had nicely posted some advice about getting a "T_ENCAPSED_AND_WHITESPACE" parse error...
So I found the line in question, after browsing through the file for ages finding nothing, and then I noticed something:
The "users browsing this forum" hack thingy...
I had: (posting small amount of code)
Code:
$username = "<b><i>$forumuser['username']</i></b>";
} elseif ($forumuser['usergroupid'] == 7) {
Of course - The little [' '] in the line:
Code:
$username = "<b><i>$forumuser['username']</i></b>";
I could have kicked my computer lol...So I removed them, and now have a great parse error free forumdisplay.php
Also - I was uploading index.php to the forum folder, and I tried to access it...Then I got a weird error, which was totally unexplained...
I then re-uploaded the basic unedited file, and re-hacked it bit by bit, using the old file as a template...
I then re-upload it for the last time, expecting that to be the error, and then it works perfectly

Ah well...Thats php for ya
