   There's nothing on line 1030 in that file for that version that would cause that error.
   
   Did it occur after an update? Or a fresh installation? Can you try and re-upload the add-on files? Also, what PHP version are you using?

   Sorry, was looking at the wrong branch.
   
   Do you have any category groups present in your installation? Or did you delete a category group recently?

   This is an upgrade from v2.11.7 to v3.5.3.
   
   I have lots of category groups, I have not deleted any recently.

   This is most likely caused by a reference to a non-existent category group in the Channel table. Not something I thought I should explicitly check for, as EE should clean up after itself.
   
   Open up mcp.low_search.php and look up line 996, which should read
   
   

   $category_fields = array();

   
   
   Above that, add a new line (inside the foreach loop) and add this block:
   
   

   if ( ! in_array($group_id, $catgroups->getDictionary('group_id', 'group_id'))) 
    { 
     continue; 
    }

   
   
   ...which should fix the issue.

   This site has been through a lot of iterations. It's an MSM site, and to move over to EE v3 (without paying a fortune) I had to delete the main site and promote another site - so there was some manual database work.
   
   I did just check and couldn't find a channel using a group that does not exist.
   
   But, anyway, you fixed worked.
   
   thanks.

   Just a heads up--I ran into the same exact error. Fresh install of the latest EE and I have ZERO categories. I don't use them. Your fix above worked for me. Might want to permanently add to your plugin (which is great by the way!).
   
   Thanks!
