Notice: Undefined offset: 2 in _entity_rules_get_type_settings() (line 518

I have the same issue.
After some debugging I found this line (line 498):
foreach ($enabled_types as $entity_type => $entity_type_info) {
where enabled_types comes from (line 488):
$enabled_types = variable_get('entity_rules_types', explode(',' , ENTITY_RULES_DEFAULT_TYPES));

To the best of my knowledge the entity_rules_types variable doesn't have any meaningful key values, so I changed the first row to:
foreach ($enabled_types as $entity_type) {

For the moment this seems to have fixed the issue, however I'd appreciate if someone more involved in the module development can confirm if my sollution is correct.

I got a similar error when trying to export entity_rules stuff to features. The components aren't listed properly via the UI although it's possible to export it by specifying the component name directly in the command line and it gets added to features.inc and works pretty much... although it does consistently throw the notices and warnings mentioned above.

Me too.

#4 and #6 work, thanks!

This issue occurs if you have enabled the module but not yet gone to the settings page at admin/config/content/entityform

It has to do with the fact that the default value for the constant "ENTITY_RULES_DEFAULT_TYPES" is this:

array(
  0 => 'user'
  1 => 'node',
  2 => 'taxonomy_term',
);

So keys there are 0, 1, 2

but the "entity_rules_types" variable is stored in this manner:

array(
  'user' => 'User'
  'node' => 'Node',
  ... whatever
);

So the keys there are "user", "node" and so on.

The problem is not solved by #6, but should be solved by saving your settings form and possibly clearing your cache.

A better solution is still needed.

Wow! Not sure what I was looking at. Sorry for this post. I'll put it back to RTBC.

Ignore previous comment.

$enabled_types contains a list of strings and has not been flipped. This should actually read:

foreach ($enabled_types as $type) {

The error has already been present before the patch, and we should take care of it as well.

Patch in #15 eliminated the error for me, thanks.

Can we get #15 committed?

Patch #15 worked for me with D7.51 and 7.x-1.0-alpha4+7-dev. It would be great if this is committed!

patch #15 work for me Thanks :)

is this committed? thanks.

@laurencefass — when a patch is committed you'll see a note in the comments with the commit ID, and the status of the issue will be changed to Fixed. Since this one still has a status of RTBC and there's no commit notice, then you know it hasn't been committed yet.
