LSC and Mailerlite conflict




Wordpress LScache Plugin: LSC and Mailerlite conflict

Last Updated on: Wed, 15 Apr 2026 00:00:02
Hi, I recently started using Mailerlite for email campaigns and the associated embedded forms. The sign-up / newsletter form is set to appear in the right-hand sidebar. However, it wont work properly if optimising JS. Now, its not the end of the world if I have to leave JS optimisation switched off but I would like to be able to just exclude the Mailerlite JS if possible. The trouble is, I just cant figure out what I need to exclude to make this work. Any suggestions as to what I should be excluding? Thank you PS: I dont have any JS optimisation on at the moment so you can see the sidebar Mailerlite form. Let me know if you want me to optimise JS so you can see (or not see!) the problem. The page I need help with: https://richiesroom.com/puppy-socialisation-plan/ Hi, Please try official-mailerlite-sign-up-forms in JS exclude box. Best regards, Hi, Thanks for the suggestion. Ive just tried that and Im afraid the form still gets removed. Is there anything else that I can try? Thanks Richie If it helps, Ive just been experimenting with the settings: Switching on JS Combine or Load JS Deferred results in the error outlined above. Switching on JS Minify or Inline JS Minify does not. Sorted! Just in case anybody else has a similar issue what I did was ? I used GTMetrix to run a report and then analysed the JS in the waterfall report. After a bit of Trial & Error I established that the following was the JS that needs to be excluded: /data/webforms/1813936/h6s1j4.js Reason: Mark as resolved
