I had the same problem and went into the code to do a quick fix. It is working on my site with my page of quotes displayed by quote id andthe random quote on each page still works. Anything else not tested…
the code is located at: wp-content/plugins/quotes-collection/quotes-collection.php
Search for the following code:
function quotescollection_displayquotes($source = "")
{
global $wpdb;
$source = html_entity_decode($source);
$sql = "SELECT quote_id, quote, author, source
FROM " . $wpdb->prefix . "quotescollection
WHERE public = 'yes' ";
if(!$source) {
$sql .= "ORDER BY quote_id";
}
Change the ORDER BY quote to ORDER BY quote_id
Hope this helps.
