5. FAQ

1. Unable to load store!

If you get this error message when you try to reach POS interface, it’s probably because you did not save POS information for your user as mentioned in the installation process.

Go in System > Permission > User > [ Select your user ]

Fill all information of “POS information” section and Save.

2. POS and MagentoClientComputer

Here a check point list to solve common problems

1 - Did you install Magento Client computer on magento? Here the online documentation.


2 - Does the option “auto print receipt” has been saved to yes in : System > Sales > Point Of Sales ?

3 - Try to run the software MCC .exe as “Administrator”

4 - Check the FTP directory rights at : System > Configuration > Advanced > Magento Client

Auto print receipt option do not work

Auto print receipt require the extension “Magento Client Computer”. This extension allow you to send the receipt to a remote printer.

But you must install it on your Magento and your computer ( Windows OS only ).

Once MCC is installed and configured you must must run the executable    MagentoClientComputer.exe

If the extension is correctly installed you should see a windows notification “last update...”

Now enable the option “auto print receipt” in POS configuration page to send the receipt during the order creation.

If the receipt is not send check the Magento Client Computer FAQ section and check your printer to handle the common issue (paper, ink, connexion etc..)

3. The request payment method is not available and please select store errors

Most of the times, that happens because the current magento user is not properly configured within Point of Sales.

To do so, you should go to System > Permissions > Users -> [Select a User ], then fill all require fields in section POS information .

Save that page, leave than go back to that page again to double-check that the data was saved indeed.

If the fields were not saved, then go into your remote server FTP for instance and rename the folder /var/cache into /var/cache_old to refresh all the caches.

4. Error processing your request Wrong Content Type

Trace:#0 /home/usr/www/magento/app/code/core/Mage/Usa/Model/Shipping/Carrier/Dhl/International.php(397): Mage::throwException(‘Wrong Content T...’)#1 /home/usr/www/magento/app/code/community/MDN/PointOfSales/Model/System/Config/ShippingMethods.php(30): Mage_Usa_Model_Shipping_Carrier_Dhl_International->getAllowedMethods()

You must save your shipping method, error message show us a problem due to the Carrier : Dhl which have a wrong content type?!

See also

Go into : System > Configuration > Sales > Shipping methods, and save the page.

Now you should be able to add / edit any users.

5. Fatal Error getBackend() on non object

PHP Fatal error: Call to a member function getBackend() on a non-object

If this error is displayed on POS screen, it’s probably because pos_shortcut attribute has not been created during the installation.

To solve this issue

Go in Catalog > Manage Attribute > Add new attribute

Attribute code : pos_shortcut

Scope : Store View

Catalog Input Type for Store owner : DropDown

Label : Show shortcut in POS

Save the attribute and refresh your POS page ( Ctrl + R )
