PHP Fatal error: require_once(): Failed opening required 'CRM/Core/ClassLoader.p

[welly]

Hello all,

I've had this problem occur before and it's happened again. It's come out of nowhere and the only resolution is to move the civicrm folder out of sites/all/modules.

-----

mod_fcgid: stderr: PHP Fatal error: require_once(): Failed opening required 'CRM/Core/ClassLoader.php' (include_path='.:/var/www/vhosts/example.com/sites/all/modules/civicrm:/var/www/vhosts/example.com/sites/all/modules/civicrm/packages:.:') in /var/www/vhosts/example.com/sites/default/civicrm.settings.php on line 304, referer: http://example.com/admin/structure/views

-----

When it's occurred before, I've unextracted a new copy of Civi into the folder and it's 5 times out of 10 fixed it. I did that this time and it failed. I can absolutely confirm the file that Civi appears not to be able to find does exist in both the locations listed in the include_path so I can't see how that is the problem.

Any help is very gratefully received! The Civi version is 4.3.5 and the Drupal version is 7.

Thanks,

welly

I don't know if there is any downside but we have actually removed those lines from civicrm.settings.php with some success. In 4.4.x there is a gotcha where you might need to clear a variable (I think there is a ticket on that).

NB - didn't see you at DrupalSouth

I might try that! No.. didn't make it to DrupalSouth this year - I'm currently back in Pommyland. Next year though..

Yeah I've been pulling those two lines out of civicrm.settings.php whenever I hit that error. I'm unsure when that change came in.

There is also a Drupal variable which may need clearing if you've moved the CiviCRM codebase - I forget the name but you can see the stored path with

Code: [Select]

drush vget civicrm (shows all variables matching civicrm) then remove it with

Code: [Select]

drush vdel civicrm_whatever_its_called.

Assuming you're referring to removing:

require_once 'CRM/Core/ClassLoader.php';
CRM_Core_ClassLoader::singleton()->register();

in civicrm.settings.php, I've done this and it's really not made any difference. In fact, the problem is even worse now.

I've seen this error when I've moved a site and not adjusted civicrm.settings.php - could that be your case?

Could not locate CiviCRM codebase. Make sure CiviCRM settings file has correct information.   

implies the global $civicrm_root is not correctly set

I'm glad you both got me to look again for a third or fourth time at the civicrm.settings.php file. $civicrm_root was incorrect. Sorry

It happens :-)
