http://forum.hkpopmusic.com/rc1b/index.php
2.3.9RC1 sucessfully installed using the 2.5 RC1b database( that means mySQL database has no problem)
http://forum.hkpopmusic.com/beta(2.39rc1)

What error did you get? I cannot see it because in the rc1b directory index.php is disabled.

Hmmm, I'm trying to install 2.5RC1b (FUDforum21_20030516) also, and I'm also getting a fatal error.

I went through all 5 of the installation steps ok, and then I deleted install.php.

When I go to http//MYDOMAIN.com/fud/ I get the following message:

Fatal error:  SQL Error has occurred, 
please contact the administrator of the forum 
and have them review the forum's SQL query 
log in /home/MYDOMAIN/public_html/fud/index.php 
on line 56


Any ideas? -Steve

Please send me the contents of the sql_errors file, which can be found in the 'errors' directory of the forum.

Oh, arggh.

I can see my FUDforum/errors/ folder, but I can't get into it -- no permissions. It doesn't seem like I can use my ftp client to change the permissions on that folder either.

And since I can't start up FUDforum on this hosted machine, I can't use FUDforum to change the permissions.

What's my next step? -Steve

Hmm can you try to login to the forum as the admin?

I don't think so, that's the problem!

Either address I go to:

http://www.MYDOMAIN.com/fud/ or

http://www.MYDOMAIN.com/fud/index.php?t=login&adm=1

I get the same result:
Fatal error:  SQL Error has occurred, 
please contact the administrator of the forum 
and have them review the forum's SQL query 
log in /home/MYDOMAIN/public_html/fud/index.php 
on line 56


The 5-step install went fine, but I've never been able to log into the forum. I'm not sure what SQL error there is, but I can see by looking at the sql admin app that 25 or so tables were created, so the install.php app was able to successfully talk to the sql server.

Is there some "backdoor" I can use to get to the FUDforum page that will allow me to un-protect the folders? Or just some simple php script? I'm curious to see that error log! Thanks. -Steve

You could try to login via the admin login panel at:
http://www.MYDOMAIN.com/fud/adm/

If that does not work, here is what you need to do.
Create (inside the directory where you've installed the forum) and run the following PHP script:
<?php
include "GLOBALS.php";
readfile($GLOBALS['DATA_DIR'] . 'errors/sql_errors');
?>


It should output the error strings.

I created and ran the script - it generated a file that appears to be encrypted somehow? The dates & times are in English, but then there's about 400 characters of gibberish following them. How can I convert these strings into something useful for debugging? -Thanks, Steve

The error messages are base64 encoded, so you need to pass them via base64_decode() function first.

Interesting, hmm, my error messages not only placed in a directory that I can't get to but they are encoded also. This sounds like great security to help prevent me from debugging my problem Razz Rolling Eyes

Okie dokie, I've translated the string:

(index.php) 1044: 
Access denied for user: 'MYDOMAIN_fuduser@localhost' to database 'MYDOMAIN_fud'<br />
Query: LOCK TABLES fud25_ses WRITE<br />
Server Version: 4.0.12<br />


Any idea what this means?

BTW, for anyone else that mioht want to interpret base64, I found a handy web site:

http://www.wc.cc.va.us/dtod/base64/default.asp

Thanks for any advice. -Steve

Normally you view messages through the error viewer and for sake of easy parsing the messages are base64 encoded.

The error is very interesting, it appears that your user account does not have permission to set LOCKs on tables. This is not a FUDforum problem, but rather something you need to ask your system admin to do for you. You need to have them give you permission to set LOCKs on your tables.

That's very interesting. I've sent a message to my webhost (www.myacen.com) asking them what's up. They tell me that locking privileges are off by default, and they're curious why the script needs to lock tables.

Rolling Eyes

In your experience, is this a common issue with hosted web sites?

Also, do many php scripts for forums, etc. need to lock database tables?

Most webhosters who support MySQL grant locking priveleges because without the ability to create table locks you cannot ensure data integrity. Especially when you can have multiple requests to the database occur in the same instance.

Well, I'm asking them to allow the table locking, but they're clearly uncomfortable. I don't get the impression they have a specific reason, it's probably just a setting that has worked well for them and it sounds like no one has ever asked about it before.

What's involved with removing the locking code from fudforum? Is it really necessary or is it just a matter or a little extra security or speed?

Thanks. -Steve

Table locking is for neither security nor speed. It basically prevents having 1 application writing data and the other trying to read the same data. Without locks this causes undefined behaviour. I am guessing your ISP had bad experience with dead locks (unreleased lock) because of some badly written code. So they came up with a 'solution' it being disabling of locking priveleges.

When I said "security" I actually meant data integrity.

At any rate, is fudforum locking these tables for any specific reason or just the general practice of being sure that some application somewhere isn't writing to the tables at the same time?

Has fudforum always done this locking? If so, then what my host is doing must indeed be rare, if this hasn't come up before.

Thanks for the help. -Steve

Good news!

My host (myacen.com) turned on the ability for table locking, and now my installation is working fine.

Thanks for helping me debug this. -Steve

FUDforum has been using table locks since the first release. When possible to avoid table locks they are not used, however in a number of instances when data is inserted they are unavoidable and therefor are used.
