    Plugin for Wordpress

    PHP
    A link to the page with the description and current work plans.

    Shortly :
    Famous cache plugins (WP Rocket, W3 Total Cache, ...) sometimes don’t help. This occurs when some combination of plugins on the site breaks them "with interpretation" and they decide that the page cannot be cacheed. They also work badly with the caching of the adjax requests because it’s difficult to realize for a universal plugin.

The cooperation with Sergey began literally immediately, after the weekend. I told what we are doing, where we are going and why we are doing everything, what Sergey professionally trained, supplemented with his vision, showed where and how wrong - very business advice and eventually started to perform tasks.
We have been working together for almost a month and a month later I note contact, professionalism and quality of work by 10 out of 10.
I recommend my business as a professional.
