Wordpress LScache Plugin: Instant Click Busts My Site
Last Updated on: Wed, 15 Apr 2026 00:00:02 When I activate Instant Click my site basically dies. The admin are becomes almost unusable and nearly impossible to navigate. http://prntscr.com/mxwgjp This topic was modified 3 years, 8 months ago by WillOfTheWeb. Hi, Could you please provide the report number ? Best regards Hi its CXSGVPFG Hi, If you revert all to default setting and only enable instant click , will it break your page when you click ? Best regards I just reset it and the same problem occurred. Hi @willoftheweb, can you find any JS on browser console or PHP error on the error page? Loads of JS errors. The problem doesnt occur until I go back to the home page and go to any other page on my site. The front end of the site is also broken at this stage.

So in this situation, we do not recommend you to use Instant Click with your site.
