First, thank you for the great plugin.
Just an issue I thought you should be aware of. After updating to WordPress 3.5.2 I tried to continue an old search.
I am seeing this error on the right hand column under include these statuses of the tools>find duplicates page
"in_array() [function.in-array]: Wrong datatype for second argument in /mysite.com/wp-content/plugins/find-duplicates/tpl/search.php on line 43"
same page between the two boxes (search settings and log) I get
"Warning: Invalid argument supplied for foreach() in /mysite.com/wp-content/plugins/find-duplicates/tpl/search.php on line 123"
I saw similar errors on the settings>find duplicates page, unfortunately did not record the exact error. I was able to remove them on that page by entering a new set of settings and pressing save.
I think it was due to me being "mid search" when I upgraded wp. Any ideas or suggestions? If no, thanks again anyway and great tool.
