Issue:

After installing the extension, I encountered serialize error on Frontend:

1 exception(s): Exception #0 (Exception): Notice: unserialize(): Error at offset 0 of 5 bytes in /home/tawfee5/public_html/app/code/Bss/OrderAmount/Model/Config/Backend/Serialized.php on line 40

Solution:

In the database, Please go to Table core_config_data and find in column path with value "sales/minimum_order/amount" -> Then, backup and remove the found row
