Errors with Rocket Loader

I installed the Rocket Loader plugins on my page with a version of Wordpress 4.0 and it gave me many errors of returns of the entries to the page. Then I updated the Worpress to version 5.0.3 and continued giving the same errors. The support of the plugins does not respond and is a paid version

The plugins do not break the design or the JavaScript of the page and the images are not affected. The speed of the page does not increase with the installation of the Rocket plugins.

The error consists of opening the home page and if the user searches for "Our offers" it seems 20 offers approximately, then tries to enter a specific offer (Fxxx) returns the page to our offers showing another series and does not show the required
