PHP fatal error
 
This pops up in my error logs every once in awhile. I've not had any complaints about anything specific not working, nor have I been online when the error occurs.

vB.com wanted me to open a ticket and disable/uninstall all mods and upload a clean vB. I don't really want to do that since a lot of my members have neurological disorders and can't cope with change well (all the back n forth breaks some of the mods they use).

Code:
PHP Fatal error: Call to undefined function fetch_phrase() in /home2/nonyabiz/public_html/includes/functions.php on line 3518
Here's lines 3468 to 3529 (in case any of the preceding code is relevant) with 3518 in red.

Code:
// #############################################################################
/**
* Fetches an error phrase from the database and inserts values for its embedded variables
*
* @param        string        Varname of error phrase
* @param        mixed        Value of 1st variable
* @param        mixed        Value of 2nd variable
* @param        mixed        Value of Nth variable
*
* @return        string        The parsed phrase text
*/
function fetch_error()
{
        global $vbulletin;

        $args = func_get_args();

        // Allow an array of phrase and variables to be passed in as arg0 (for some internal functions)
        if (is_array($args[0]))
        {
                $args = $args[0];
        }

        if (class_exists('vBulletinHook', false))
        {
                ($hook = vBulletinHook::fetch_hook('error_fetch')) ? eval($hook) : false;
        }

        if (!function_exists('fetch_phrase') AND !VB_API)
        {
                require_once(DIR . '/includes/functions_misc.php');
        }

        if ($vbulletin->GPC['ajax'])
        {
                switch ($args[0])
                {
                        case 'invalidid':
                        case 'nopermission_loggedin':
                        case 'forumpasswordmissing':
                                $args[0] = $args[0] . '_ajax';
                }
        }

        // API only needs error phrase name and args.
        if (defined('VB_API') AND VB_API === true)
        {
                return $args;
        }

        $args[0] = fetch_phrase($args[0], 'error', '', false);
        if (sizeof($args) > 1)
        {
                return call_user_func_array('construct_phrase', $args);
        }
        else
        {
                return $args[0];
        }
}

What version vb are you running? Do you have any plugins using the hook location error_fetch ?

John Lester 09-08-2011 06:55 PM
4.1.5 and I don't know if any of the plugins use that hook :( Can I find out without having to go through every line of code in every file?

Lynne 09-08-2011 09:06 PM
Just look at the Plugin Manager > look at the column where it says hook location.

John Lester 09-08-2011 10:05 PM
There are none that hook into error_fetch

Lynne 09-09-2011 01:58 AM
Are you using a language pack?

John Lester 09-09-2011 03:03 AM
No, no language packs used.

EDIT: I used winmerge to compare a clean file and the live file and they are identical. So we know nothing is wrong with the file itself.

Could a style be causing this? I do have a few styles installed.

EDIT 2: This is how long and how often this error has been occuring. As you can see it's erratic and I can't find any other errors or slow queries to correspond with the dates and times.

It doesn't look like it happens very often. But, some phrase seems to be missing. I supposed your could reinstall your language file via tools.php. But, I don't know how much I would worry about an error that only happens a couple times a week.

John Lester 09-09-2011 07:25 PM
Yea I'll leave it be for now thanks Lynne :)
