Installation:
Open PHPMyAdmin, create a database and import hashtag.sql.
Open config / class / needy_class.php and fill in your PDO, path and email.
Open config / declare.php, config / class / needy_class.php & public / js / modules.js and replace the DIR variable containing my root path with your root path. (Note: don't add a slash at the end!).
Open .htaccess, go to line 17 and replace it with your root path.
If the Back Time function is not working correctly (forward or backward), go to config / class / time.class.php and play around with line # 8. Enjoy !!
