If I have a single item in cart, getting an error of no payment method selected.  If I have more than 1 item or if I have 2 and delete one in the cart, I can check out via paypal.

Any suggestions??

Is there a way to configure so that if a specific option is selected that an additional fee is applied.  ie any item with red option, add $10.  IF multiple items have "red" option, only one $10 fee applied.

I installed via Softaculous onto the host qwk.net.  After install, when try to connect to the store or admin, I get an error of "There has been a critical error processing your request".

I have opened the error log in system/logs/ and have the following error:

2015-12-15 21:17:11 - warning:  AbanteCart core v.1.2.5 mysqli::mysqli(): (HY000/2000): mysqlnd cannot connect to MySQL 4.1+ using the old insecure authentication. Please use an administration tool to reset your password with the command SET PASSWORD = PASSWORD('your_existing_password'). This will store a new, and more secure, hash value in mysql.user. If this user is used in other scripts executed by PHP 5.2 or earlier you might need to remove the old-passwords flag from your my.cnf file

Any ideas on what I need to do?  Sorry, I am a newbie to all this fun!!
