# SyntaxError: Unexpected identifier ‘anti_cache’

 * WPLC breaks javascript and I get the error message: SyntaxError: Unexpected identifier‘
   anti_cache’. I only noticed it in Safari. Seems to be a problem using the let
   keyword. On line 425 of wplc_server.js changing “let anti_cache = Date.now();”
   to “var anti_cache = Date.now();” seems to fix it.

 * Hi there,
 * Thank you for getting in touch with us and reporting this.
 * That’s strange because the latest version of Safari supports let variable. We’ll
   test it and fix in the next plugin version.
 * Thank you for your time in this.
 * Best regards,
    Jarek

 * Yep, I guess I should update my Safari then (I rarely use it), I was using version
   9.1.2 and let is only since Safari 10.
