Greetings,

Last night, I eagerly installed the following hacks that I found on this site:

Number of posts, Number of comments

Smilies into the commentspopup and comments files

Smilies in the Post and Edit region

and Last Comments

Now I have a problem....

If I create a new entry or comment on an entry and push "POST" or "SUBMIT" or "BLOG THIS", then I get an error message.

An example is what I just received when I tried to comment on an entry.

Could someone please help me? I thought that it might have been the "LAST COMMENTS" script because the error message says something about b2functions.php:960. So I deleted the include statement on b2function and the call statement on where I want it to show up but I still get errors.

Thanks!

I deleted the Last Comments script COMPLETELY.

I kept the smilies in the posts and in the comments. I have also kept the total posts and total comments features.

I erased the small line of code (WHICH ORIGINALLY WORKED) out of b2functions. This code was for the Last Comments script.

THIS IS THE ERROR MESSAGE THAT I STILL GET. If someone tries to login or if they post a comment, I get the same message but it references, for example, /blog/b2edit.php on line 176 if someone tries to POST a new entry.

Thanks for anyone who can offer a pointer.

Have you got any spaces or empty lines after the final ?> of b2functions.php?

The problem starts on line 960 of b2functions.php, so check near this line, but the cause could be elsewhere in the file.

If this doesn't help, then go back to the original b2functions.php you downloaded and make any changes one at a time, testing to see what happens until you have found the cause of the problem. Tedious, but possibly the only way to dind the source of the error.

I am a newbie and had no idea that it was just a few spaces causing me the problems. I had about four spaces or lines following the last ?>.

Thanks so much for taking the time to read through my post and then replying!

You be da man!
