strange, i got babel on several sites and updated to the latest version without any problem.
when does this error occur?
did you tried to reinstall babel?
has you site maybe been hacked and files manipulated that lead to this problem?
actually there are alot of hacked sites, if you need help the modx comunity on slack is a good place to get it.

Yes I did reinstall babel. I am on version 3.0.0 and I have four different contexts (web, fr, it, en). The error occurs when I want to edit a resource in the backend, it happens with each resource, the screen goes totally blank except the error. The site has not been hacked. But I updated from 2.4.3 straight to 2.6.5.

I have modx 2.6.5, and $resource is array in plugin. Why?
Insert before $linkedResources = $babel->getLinkedResources($resource->get('id')); (54 line) for fix.

if(is_array($resource)) {
     $resource = $modx->getObject('modResource', array(
            'id' => $resource['id']
     ));
}

This is fixed with 3.2.0.
