Catchable fatal error: Object of class stdClass could not be converted to string in /home/monarch/public_html/libraries/joomla/html/parameter.php on line 105

Once I've added a product to the cart and then proceed to checkout I get the above error.

I don't have any overrides that I know of. What sort of thing might be overriding the view?

I can give you access to this site if you need it. Did you find the item for sale, it's a little hidden? www.monarcheducare.org/index.php?option=...&view=item&Itemid=10

I turned of sh404SEF url's to make sure that wasn't causing the problem.

Sorry, got tied up with a few other projects... back to looking at this now. I see you created a user during your test, I've increased the access rights for that user so you can get into the back end. I will send you the back end url and ftp logins via private message.

Hi,

Solved !
It was an incompatible code with Joomla 1.5 in the address class.

Perfect, I can process an order now... thank you. However, I've noticed (and I don't know whether this is related) that when I go into the orders list in the back end of Hikashop, although it says it is showing "Results 1-3 of 3", no actual orders are showing up.

Hi,

Please check in the database if there is any orders presents.
This is potentially due to the previous error, some orders have maybe not been fully completed.

Yes, there are orders in the DB in the jos_hikashop_order table.

I actually created these orders AFTER the fix above as I was unable to process an order before.

When I try to visit the orders page in the back end of the website with debug mode on, I get the following error...

500 - An error has occurred.

JDatabaseMySQL::query: 1253 - COLLATION 'utf8_general_ci' is not valid for CHARACTER SET 'latin1' SQL=SELECT a.*,b.*,c.*,IFNULL(c.name COLLATE utf8_general_ci,CONCAT_WS(' ',d.address_firstname,d.address_middle_name,d.address_lastname)) AS hikashop_name FROM jos_hikashop_order AS b LEFT JOIN jos_hikashop_address AS d ON b.order_billing_address_id=d.address_id LEFT JOIN jos_hikashop_user AS a ON b.order_user_id=a.user_id LEFT JOIN jos_users AS c ON a.user_cms_id=c.id WHERE (b.order_type='sale') ORDER BY b.order_id desc LIMIT 0, 20
