Warning: Illegal string offset ‘color_class_term_meta’

I got this error Warning: Illegal string offset ‘color_class_term_meta’ in C:\xampp\htdocs\CroWrestling\wp-content\themes\newsever\inc\template-tags.php on line 32
after I tried to create a new category. I haven’t changed anything in the code so I dont know why it suddenly gave me the error. here’s the code:

if (!function_exists(‘newsever_post_categories’)) :
function newsever_post_categories($separator = ‘&nbsp’)
{
$global_show_categories = newsever_get_option(‘global_show_categories’);
if ($global_show_categories == ‘no’) {
return;
}

// Hide category and tag text for pages.
if (‘post’ === get_post_type()) {

global $post;

$post_categories = get_the_category($post->ID);
if ($post_categories) {
$output = ‘<ul class=”cat-links”>’;
foreach ($post_categories as $post_category) {
$t_id = $post_category->term_id;
$color_id = “category_color_” . $t_id;

// retrieve the existing value(s) for this meta field. This returns an array
$term_meta = get_option($color_id);
$color_class = ($term_meta) ? $term_meta[‘color_class_term_meta’] : ‘category-color-1’;

$output .= ‘<li class=”meta-category”>
name)) . ‘”>
‘ . esc_html($post_category->name) . ‘

‘;
}
$output .= ‘‘;
echo $output;

}
}
}
endif;

There is also another error in the categories when I try to edit them in the Color Class. This is the error:

Warning: Illegal string offset ‘color_class_term_meta’ in C:\xampp\htdocs\CroWrestling\wp-content\themes\newsever\inc\hooks\hook-meta.php on line 203

and here’s the code:

if (!function_exists(‘newsever_taxonomy_edit_meta_field’)) :
// Edit term page
function newsever_taxonomy_edit_meta_field($term)
{

// put the term ID into a variable
$t_id = $term->term_id;

// retrieve the existing value(s) for this meta field. This returns an array
$term_meta = get_option(“category_color_$t_id”);

?>
<tr class=”form-field”>
<th scope=”row” valign=”top”><label
for=”term_meta[color_class_term_meta]”><?php _e(‘Color Class’, ‘newsever’); ?></label></th>

<?php
$cat_color = array(
‘category-color-1’ => __(‘Category Color 1’, ‘newsever’),
‘category-color-2’ => __(‘Category Color 2’, ‘newsever’),
‘category-color-3’ => __(‘Category Color 3’, ‘newsever’),

);
?>
<select id=”term_meta[color_class_term_meta]” name=”term_meta[color_class_term_meta]”>
<?php foreach ($cat_color as $key => $value): ?>
<option value=”<?php echo esc_attr($key); ?>”<?php selected($term_meta[‘color_class_term_meta’], $key); ?> ><?php echo esc_html($value); ?></option>
<?php endforeach; ?>
</select>
