Hi Cici,
I just installed the latest 5.12.3 plugin version and tested a PHP 8.0 upgrade and am receiving a “There has been a critical error on your website” message when attempting to view the site. When I checked the site error logs, I’m getting the following:
PHP Parse error: syntax error, unexpected token “\\” in …/wp-content/plugins/store-locator-le/include/module/text/SLP_Text.php on line 239
