We've just updated a site to use LS3.5.1 from 3.3.2 and I'm getting the following errors. EE is 2.9.0 - an upgrade is an option as the site is brand new.

Severity: Notice

Message: Undefined index: 7

Filename: keywords/lsf.keywords.php

Line Number: 869

We're using Structure, so for the link to the page we want to use {page_uri}. The results are all working as expected - we're just getting these errors.

I've been into each collection and added the language option. I've re-indexed the collections and switching {page_uri} for {auto_path} removes the error notices.

I've also deleted the module entirely and re-uploaded to make sure we're not missing anything in the filters folder which I've seen could be an issue.

Any thoughts?

I'll get the error fixed in the next version. For now, open up /low_search/filters/keywords/lsf.keywords.php and look up line #869, which reads:

$row['auto_path'] = $this->_urls[$row['channel_id']] . $row['url_title'];

Change that to:

$row['auto_path'] = @$this->_urls[$row['channel_id']] . $row['url_title'];

Note the @ added before $this->.
