SERIOUS problems with Chibifurs
 
Okay for the past three months, Chibifurs has been dealing with some severe code issues. As seen here: http://www.chibifurs.com/ we are unable to get into the adopts half of the site. We have gone through the rings with our service providers who have essentially told us to come to you. I have included all screenshots and discussions we have had with them to help.

Hi ----,

This is the error that comes about when an existing site (one with a valid /home/chibifur/public_html/classes/class_database.php ) points to a database that no longer exists.

Check /home/chibifur/public_html/classes/class_database.php and make sure that the database listed in there is able to be connected .

Regards,
Arun

Hi,

Please be informed that the database table chibifur_adopts2.adopts_settings is missing in your database .
Please restore your complete database.

Regards,
Diwakar

--------------------------------------

It wasn't there. I re-uploaded it from one of my backups.

http://fc09.deviantart.net/fs70/f/20...sh-d5qpmur.png


---------------------------------------

Hi ,

We have checked your database but the Table 'chibifur_adopts2.adopts_settings' does not exist in it.

But /home/chibifur/public_html/classes/class_database.php script requires such a table.

Please contact your developer regarding this.


Regards,
Diwakar

---------------------------------------


We are now at the point where we may have to close down the site because of all of this and are begging for help.

Hall of Famer 03-24-2013 05:01 PM
well there is nothing wrong with the database class file, it has been untouched since Mys v1.3.1 and it still works the same way in Mys v1.3.3. Did you check from phpmyadmin whether the table prefix_settings has the necessary entries? It may be present but is actually an empty table?

Anyway, what error message do you get exactly on your site? Also you may want to check your config.php file to see if anything is abnormal from there. I wont be surprised if your host does not really understand the situation at all.

GuardiansWish 03-24-2013 05:23 PM
From what I can see, the table is fine but I'm pretty lost when it coes to the database and I generally leave it alone other than making back ups. An yea, I was getting that feeling too.

heres the error:

Fatal error: Uncaught exception 'Exception' with message 'Database error 1054 - Unknown column 'ip' in 'where clause'' in /home/chibifur/public_html/classes/class_database.php:161 Stack trace: #0 /home/chibifur/public_html/classes/class_database.php(81): Database->_query('online', Array, 'select', 'username = 'Vis...') #1 /home/chibifur/public_html/classes/class_online.php(57): Database->select('online', Array, 'username = 'Vis...') #2 /home/chibifur/public_html/inc/init.php(33): Online->update() #3 /home/chibifur/public_html/index.php(3): require('/home/chibifur/...') #4 {main} thrown in /home/chibifur/public_html/classes/class_database.php on line 161

Hall of Famer 03-24-2013 08:58 PM
umm is this the only error message you get? Looks like there is something wrong with the who's online system, it is not supposed to be loading the column IP for guest users. But if I recall correctly, your site was running Mys v1.3.1 wasnt it? Why do you get error message with a class available in Mys v1.3.2? Did you try to upgrade? If so, it seems to me that the upgrade failed.

GuardiansWish 03-24-2013 09:55 PM
We were running 1.3.1 and tried to get to 1.3.2.

It worked for a few days and then went down. We were one of the first sites to get it up. I don't know if there are any other errors hiding because we can't get to the other pages. If it did fail, what does that mean for the site? Is there a way to go back down, re-upgrade, go to 1.3.3 or something along those lines? Or is there a way to possibly fix the error without such drastic measures.

I see, so it was indeed due to a failed upgrade. Yes you can always reupgrade, but keep in mind that you need to run the upgrader script, do not just upload files to overwrite old files and expect everything to work. It does seem to me that you are missing some database columns made available in Mys v1.3.2.

After discussion with my fellow admins, we tied to update again to 1.3.2 but it failed. We have gone ahead and started from scratch and plan to do so with 1.3.3. We thank you for doing your best to help us with this matter <3

Well I wonder why your upgrade failed in the first place? Did you happen to modify your script files? I mean, by editing the php files? If so, you will have to manually upgrade the script rather than go for the shortcut upgrader approach.

I'm not quuite sure. We hadn't modified anything but the template for our skin and it was up for a few days and running decently smoothly before it crashed on us.
