 * Hey guys, I have 2 wordpress blogs sharing the same user database and I would
   like to have my PHPBB instllation(also sharing the same database) use the users
   from my wordpress installations.
 * I installed and configured PHP BB options and everything seems fine:
 *     ```
       auth_wpbb.php 	0.7.1 	0.7.1 	OK
       common.php 	0.7.1 	0.7.1 	OK
       common-orig.php 	- 	Original 	OK
       Configurations
       Auth Mode 	wpbb 	wpbb 	OK
       Wordpress Path 	Variable 	ideviceblogr/ 	OK
       ```
   
 * But now when I try to log into my admin panel on PHPBB I get tons of errors and
   the admin panel doesn’t even show up:
 *     ```
       [phpBB Debug] PHP Notice: in file /home7/iphoneb1/public_html/wp-content/themes/therapy/includes/theme-widgets.php on line 8: Use of undefined constant woothemes - assumed 'woothemes'
       [phpBB Debug] PHP Notice: in file /home7/iphoneb1/public_html/wp-content/plugins/wp-ban/wp-ban.php on line 108: Undefined offset: 1
       [phpBB Debug] PHP Notice: in file /includes/auth/auth_wpbb.php on line 14: Undefined index: mode
       [phpBB Debug] PHP Notice: in file /adm/index.php on line 150: Cannot modify header information - headers already sent by (output started at /includes/functions.php:3706)
       [phpBB Debug] PHP Notice: in file /adm/index.php on line 152: Cannot modify header information - headers already sent by (output started at /includes/functions.php:3706)
       [phpBB Debug] PHP Notice: in file /adm/index.php on line 153: Cannot modify header information - headers already sent by (output started at /includes/functions.php:3706)
       [phpBB Debug] PHP Notice: in file /adm/index.php on line 154: Cannot modify header information - headers already sent by (output started at /includes/functions.php:3706)
       ```
   
 * The problems go away if I delete common.php and rename common-orig.php back to
   common.php but then obviously the plugin doesnt work…. any ideas?
 * Thanks in advance!

 * hi, you can try delete all lines under first `<?php` and all lines after last`?
   >`. But it’s errors can be after you editing `common.php` or other files with
   notepad or others programs who can change coding and add the BOM (byte order 
   mark). For view it use notepad++ or others programmers notepads.
 * And view all plugin files for BOM.
