Combining multi filter and pagination with url filtering unsecsessful

[macreixa]

Hello, I was able to implement URL filtering based on your tutorial, but when I tried to integrate it with multifiltering and pagination, I was unsuccessful.

I leave here the code that is working ok (without url filtering), can you lead me to a solution, as the instructions I found online were not effective.

<section id="filters" class="filterbox main-grid">
    <form class="controls">
        <div class="control-search">
            <fieldset data-filter-group>
                <input type="text" data-search-attribute="class" placeholder="Search"/>
            </fieldset>
        </div>
