Changing pics in Avada theme redirects to a 404


I recently updated wordpress to 5.8 and PHP to v8. Suddenly, when I want to add, change, or edit pictures in the Fusion theme builder, I get redirected to a 404 with this error:

Notice: Use of undefined constant php – assumed ‘php’ in /home/c0gf5875uk7l/public_html/wp-content/themes/Avada/404.php on line 23

Here is the PHP for the 404.php file this error is calling out:

<?php get_header(); ?>
    <div id=”content” class=”full-width”>
        <div id=”post-404page”>
            <div class=”post-content”>
                <div class=”fusion-title title”>
                    <h2 class=”title-heading-left”><?php echo __(‘Oops, This Page Could Not Be Found!’, ‘Avada’); ?></h2><div class=”title-sep-container”><div class=”title-sep sep-double”></div></div>
                <div class=”fusion-clearfix”></div>
                <div class=”error_page”>
                    <div class=”fusion-one-third one_third fusion-column spacing-yes”>
                        <div class=”error-message”>404</div>
                    <?php/*<div class=”fusion-one-third one_third fusion-column spacing-yes useful_links”>
                        <h3><?php echo __(‘Here are some useful links:’, ‘Avada’); ?></h3>

                        if( $smof_data[‘checklist_circle’] ) {
                            $circle_class = ‘circle-yes’;
                        } else {
                            $circle_class = ‘circle-no’;
                        wp_nav_menu(array(‘theme_location’ => ‘404_pages’, ‘depth’ => 1, ‘container’ => false, ‘menu_id’ => ‘checklist-1’, ‘menu_class’ => ‘error-menu list-icon list-icon-arrow ‘ . $circle_class )); ?>
                    <div class=”fusion-one-third one_third fusion-column spacing-yes last”>
                        <h3><?php echo __(‘Search Our Website’, ‘Avada’); ?></a></h3>
                        <p><?php echo __(‘Can’t find what you need? Take a moment and do a search below!’, ‘Avada’); ?></p>
                        <div class=”search-page-search-form”>
                            <form class=”searchform seach-form” role=”search” method=”get” action=”<?php echo home_url( ‘/’ ); ?>”>
                                <div class=”search-table”>
                                    <div class=”search-field”>
                                        <input type=”text” value=”” name=”s” class=”s” placeholder=”<?php _e( ‘Search …’, ‘Avada’ ); ?>”/>
                                    <div class=”search-button”>
                                        <input type=”submit” class=”searchsubmit” value=”” />
<?php get_footer(); ?>


Anyone have a clue as to why this is happening?
