GRupal Meeting

Thanks to everyone for the great time. :-)

I see great things coming out of both groups.

When I click Administer in the navigation pane of my Drupal 6.2 site (cefliberia.org), I get this error:
Fatal error: Call to undefined function lock_acquire() in /homepages/1/d93630158/htdocs/CEFL/sites/all/modules/drupal-6.26/modules/system/system.module on line 810

So I looked up the offending file. I'm clueless. I want to ask, What did I do wrong? Instead I'll ask, How do I fix this?

Here is the section containing line 810.
/**
* Collect data about all currently available themes.
*
* @return
* Array of all available themes and their data.
*/
function system_theme_data() {
$write_database = TRUE;
// If lock not acquired, return $files data without writing to database.
if (!lock_acquire('system_theme_data')) {
$write_database = FALSE;
// Wait for the parallel thread to be done so we are more likely
// to get updated and consistent data.
lock_wait('system_theme_data');
}
// Scan the installation theme .info files and their engines.
$themes = _system_theme_data();
foreach ($themes as $key => $theme) {
if (!isset($theme->owner)) {
$themes[$key]->owner = '';
}
}

Line 810 is:
if (!lock_acquire('system_theme_data')) {

Good catch!
