Try php 7.0. If they don't go away, try applying the same ideea for all of them , with isset.
Prefer to be on Ver 7.1 only.. Which line to change and which file ? with
if( isset($item_id['fk_i_item_id'])) $num = $item_id['fk_i_item_id'];
Is it /home/scorp4hj/public_html/postfreeonline.com/oc-includes/osclass/helpers/hDefines.php
and line No.491 to 499
Code line 488 to 508
$url = osc_get_preference('rewrite_item_url');
if( preg_match('|{CATEGORIES}|', $url) ) {
$sanitized_categories = array();
$cat = Category::newInstance()->hierarchy($item['fk_i_category_id']);
for ($i = (count($cat)); $i > 0; $i--) {
$sanitized_categories[] = $cat[$i - 1]['s_slug'];
}
$url = str_replace('{CATEGORIES}', implode("/", $sanitized_categories), $url);
}
$url = str_replace('{ITEM_ID}', osc_sanitizeString($item['pk_i_id']), $url);
$url = str_replace('{ITEM_CITY}', osc_sanitizeString($item['s_city']), $url);
$url = str_replace('{ITEM_TITLE}', osc_sanitizeString(str_replace(',', '-', $item['s_title'])), $url);
$url = str_replace('?', '', $url);
if($locale!='') {
$path = osc_base_url().$locale."/".$url;
} else {
$path = osc_base_url().$url;
}
} else {
$path = osc_item_url_ns($item['pk_i_id'], $locale);
}
