Guest posting doesnt work?

Post by AbbeyG » Mon Mar 04, 2013 9:35 am

I am not sure why, but in my forum, I have one forum that is ear marked for guests. While I was looking to make sure that every thing is fine (the board hasnt opened, so there is a lot of testing going on :D). I found out that guest posting doesnt work. When ever I try to post as a guest, it shows a blank white screen in Mozilla and a 'Server Not found' error in Chrome.

I am sure it isnt related to server because I can post just fine in my admin account as well as on the test account. Here is my forum: http://theriddlediary.empirehostings.ne ... /index.php

'Your first forum' is the guest friendly forum.

This is what Chrome returns
Server error
The website encountered an error while retrieving http://theriddlediary.empirehostings.ne ... e=post&f=2. It may be down for maintenance or configured incorrectly.
Here are some suggestions:

I checked on a test board on a local host which uses the same files as I do on my forum and here is the error I get:

Fatal error: Cannot redeclare user_get_id_name() (previously declared in E:\theriddlediary\xampp\htdocs\phpBB3\includes\functions_user.php:27) in E:\theriddlediary\xampp\htdocs\phpBB3\includes\functions_user.php on line 82

Use Crimson Editor or some other appropriate editor to search across all the .php files (the root folder and the includes folder and children) for the string:

Code: Select all

function user_get_id_name

I dont know what children means, but I have searched for the function in all files in my root and inlcudes folder [well not the subfolders in includes folder, like hooks, search, db, diff (is that what you mean)].

I didnt find that function in any of the files I searched except in the functions-user.php file.

I cross checked with all folders. None of it had that function except for the function_user.php file.
