Wordpress LScache Plugin: GTMetrix tells me to defer parsing JS even if the setting is ON
Last Updated on: Wed, 15 Apr 2026 00:00:02 I have made performance test of my web site in GTMetrix and one score is Grade C (74) related to Defer parsing Javascript recommandation. https://gtmetrix.com/reports/www.digitalking.it/5GSBim0Q I already had Load JS Deferred set ON and Exclude JQuery OFF in the Optimize settings. I have purged all the cache and re-run the test but with the same result. How i can solve this? Thanks This topic was modified 4 years, 2 months ago by simbian. It looks like your JS isnt deferred yet. Do you mind to give a report number so we can go through your settings? You cant reach from the link i posted? https://gtmetrix.com/reports/www.digitalking.it/5GSBim0Q So i assume the report number is 5GSBim0Q Thanks Apologize for ambiguity. The report number I meant is from LSCWP, please follow https://wordpress.org/support/topic/how-to-get-help/ Ops sorry, the report number is: RVSXRNWA Thanks for the support. Hi, Could you please try for a minute there, disable all other plugins and purge cache , and check if it is deferred? Best regards, Hi, thank you for the suggestion, finally i have found the culprit, its the Ginger EU Cookie Law plugin that dramatically decrease performances YSlow Score. Is there something that i could do to avoid it or have to look for another plugin? I will report it to plugin author. Thanks. Hi, Could you please enable debug log , and see what is causing/preventing JS defer ? Best regards, Hello, I dont understand very well the debug.log anyway here is it https://file.io/W6bPu2 From Chrome Development tools i see 3 requests about the Ginger plugin https://imgur.com/y4qY2hj Thanks. Hi, My apologize for late response. Could you please submit a ticket here , and seems we need to dig deeper for this. Best regards, Hello, dont worry i solved using another GDPR plugin. Using Cookie Notice plugin seems all ok. Hi, Glad to know. Anyway , I will spend sometime on that plugin and see if I can find anything. Best regards, Hi, ok thank you!
