1. Install with demo data
2. Try to add upgrade if possible.
3. Below link explains why we dont give upgrades to abantecart:
http://docs.abantecart.com/pages/upgrade/manual.html
(i.e. it need to modify dbprefix in upgrade.sql file provided in upgrade package)
4. Remove the INSERTS FROM `messages` table which states to delete the install directory
5. select mysqli
6. PHP REQUIREMENT LINK : http://docs.abantecart.com/pages/install/system_requirements.html# and also check index.php MIN_PHP_VERSION constant.
7. Select the Novator theme while installing manually.
8. Check and move the images which are not getting created though softaculous in /resources/image/*
9. In some tables there is collation appended i.e  COLLATE=utf8mb4_0900_ai_ci (this is server specific default collation, and can be verified from phpmyadmin under 'Variables'). Check for the tables which have collation other than 'COLLATE=utf8mb4_unicode_ci', which is kept default by script and remove the line i.e COLLATE=utf8mb4_0900_ai_ci i.e COLLATE={{SERVER_DEFAULT_COLLATION}}. These entries are made again post installation through Softaculous.
