Title: Plugin causing High CLS Last modified: May 20, 2021 --- # Plugin causing High CLS * Resolved [knicolas](https://wordpress.org/support/users/knicolas/) * (@knicolas) * [5 years ago](https://wordpress.org/support/topic/plugin-causing-high-cls/) * Hi, I am inquiring about the cumulative layout shift produced by this plugin. for 0.02, the CLS goes up to 0.57. * I tested in 2 websites and this plugin is the cause of the CLS. * Any ideas on how or why this is happening. The plugin is great and so lightweight, but the impact on CLS is just tremendous. * Any suggestions on reducing the CLS due to this plugin will be appreciated.

With cleantalk its 0.570. * Hope you can fix this soon, because i tried using a firewall to replace cleantalk, but cleantalk is clearly better. i will just suffer through the high CLS. * Please do try to have a fix, as CLS will be a ranking factor by June 2021, just a few days from now. No pressure though, but since you were able to make a wonderful product, it’s likely that you will be able to fix the issue. * Thanks! - This reply was modified 5 years ago by [knicolas](https://wordpress.org/support/users/knicolas/). * Plugin Support [katereji](https://wordpress.org/support/users/katereji/) * (@katereji) * [5 years ago](https://wordpress.org/support/topic/plugin-causing-high-cls/#post-14465191) * Hello, [@knicolas](https://wordpress.org/support/users/knicolas/) Could you contact us by our private Ticket System ([https://cleantalk.org/my/support/open](https://cleantalk.org/my/support/open)) for further investigation?
