Error message after adding character removal script

[ca_jmccolley30Participant]

I tried to add the script to remove characters from search string in this article:
https://knowledgebase.ajaxsearchpro.com/miscellaneous/other/replace-or-remove-characters-from-search-phrase
The removal seems to be working but if I hit enter with nothing in the search box I get this error on the Woocommerce shop page:
Warning: count(): Parameter must be an array or an object that implements Countable in /home/customer/www/dev.circuitassembly.com/public_html/wp-content/themes/divi-child/functions.php on line 40
at the top of the results page.

Can you please tell me what is wrong?

Hi,

That script will not work with empty removals. Instead of the custom code for that, try the built in features here: https://i.imgur.com/HzlV4E0.png
