===========================================================================
1. When I add new forums or load the amdin page for a forum I get a
message like:
Warning: Failed opening '/home/phorum/admin/forums/5.php' for inclusion in
/home/phorum/admin/index.php on line 440
---------------------------------------------------------------------------
1. You need to be sure your run the .sql file for your database. See the
readme, section 1, number 2.
2. Be sure the web server can write to the forums dir. See the readme,
section 1, number 4.
2. When I post a new message, I get "Error getting nextval".
---------------------------------------------------------------------------
Check your DB connection using the admin. If that reports no connection,
check your database values in the Master Settings. If they appear correct,
check that you have given the correct permissions in your database.
3. I keep getting a warning about headers being sent.
---------------------------------------------------------------------------
You most likely have a newline after ?> at the end of a file. If you have
edited any files check that there is no whitspace in them.
4. I get errors that say "Bad Message Destination".
Emails are not getting sent from Phorum.
---------------------------------------------------------------------------
Some servers do not like sending mail with the To: field empty. If you get
errors on posting about email, you will have to edit post.php3:
mail("", "$subject", $forum_url."$r.....
change to:
mail("some@address", "$subject", $forum_url."$r.....
The bad part is that that email has to go somewhere. If you can setup some
address that can be auto deleted do that. Otherwise you may want to comment
out the lines following in form.inc:
colspan=2 width="100%" nowrap align="left">
This is actually only 3 lines in the code but has to wrap here.
5. What files do I customize to change Phorum to fit my site.
---------------------------------------------------------------------------
include/header.php
include/footer.php
You can have multiples of these. Simply name the files
header_config_suffix.php where config_suffix is the vale you gave Config
Suffix in the admin when creating the forum. This also works with:
include/censor.php -> censor_config_suffix.php etc...
include/bad_names.php
include/bad_emails.php
include/bad_hosts.php
6. What permissions does Phorum need from the database?
---------------------------------------------------------------------------
Select, Insert, Update, Delete, Alter Tables,
Create & Drop Tables.
7. What is $cutoff?
---------------------------------------------------------------------------
It was discovered that some queries were selecting the whole table. In our
case, 98,000 rows. MySQL did not like this at all. So, in lieu of a better
solution, we put in this cutoff to limit the rows it selects. You see, a
limit clause in a query does not limit the rows selected, only the rows
returned. Therefore a query like:
select * from table where id<1000200 limit 10
returns 10 rows, but to get those 10 it would select every row with an id
less than 1000200. In this case it could be 1000199 rows. So we made it
now look like:
select * from table where id<1000200 and id>(1000200-$cutoff) limit 10
Now the max you will have selected is $cutoff. I picked 800 because it will
be fine 99.9% of the time.
If someone wanted to display more than 800 messages on a page, they would
need to up this.
8. I need to use .php3 or some other extension, not .php.
---------------------------------------------------------------------------
The extension .php will be the prefered default extension for all new
version of PHP starting with version 4. It is the extension used by the
PHP team and Zend.com. For this reason, Phorum comes with this extension.
The easiest way is to use this extension is to make Apache or your
webserver parse these as PHP files. In Apache you need to add a line like:
AddType application/x-httpd-php3 .php
If that is not an option, you can change it by following these three
steps: (you can substitute whatever you need instead of .php3)
1. Rename admin/index.php to admin/index.php3
2. Edit common.php and change $admindir to index.php3.
3. Rename all the .php files in the main Phorum dir (index.php, list.php,
etc.) to the new extension WITH THE EXCEPTION OF common.php.
4. Go to the admin through your browser. Login in to the Master Settings
(if you have not set the password yet it will take you there without
logging in). Select Phorum Setup, then File/Paths. Change the File
Extension to .php3 and hit update.
9. Phorum complains about not being able to open files.

If you are seeing errors like:
Warning: fopen("admin/forums/1.php","w") - Permission denied in
/home/forum/admin/index.php on line 175
You most likely did not set up the permissions correctly. Please read the
documentation again.
