I’ve made a research with dev and live site, the problem with search is in your plugin. I’ve updated woo storefront theme and woocommerce to latest versions without updating SLP and Store Locator Plus :: Pro Pack and older versions of them (4.5.06 and 4.5 for pro pack) still work OK with search. When installing newer versions (4.5.08 and 4.5.07 for pro) it stops searching and I’m getting Ajax blocked error.
/wp-admin/admin-ajax.php 500 (Internal Server Error)
debug log shows:
[09-Jul-2016 16:18:56 UTC] PHP Fatal error: Call to undefined function array_column() in /home/xxx/public_html/dev/wp-content/plugins/store-locator-le/include/class.ajax.php on line 356
Your older version shows no errors.
Please fix.
