I can't insert or modify data in my store / Operation must use an updateable query

In 99% of the cases this problem is related with permissions trobles with Access databases.
You have to give executing permission to the /comersus and /comersus/store
folder and all permissions to comersus/database/ and comersus.mdb file.
You can also download a free Utility named Diagnostics and Tools and run the write test.
You can find more details about permissions procedure in Comersus User's Guide.

I can't login to my BackOffice

If you are receiving the message "Authentication data wasn't received", that usually means that some database trapped error is happening.
It could also means that the user and/or pass are not being received by comersus_backoffice_login.asp script due to a customization, change of form fields, etc.
Try to download Diagnostics and Tools and run all read and write test. If everything is ok, then you can try to Reset the password from there. Remember to delete the Diagnostic and Tools folder to avoid intrusions at a later time.

I can't configure e-mail settings

First of all determine which e-mail components are installed in your server (ask your webmaster). Then you can download
Diagnostics and Tools and run the e-mail test to try different configurations of component, SMTP server and e-mail from.
Sometimes everything is correct but the e-mails are not being sent due to Relay Problems. That means that the e-mail account used as the Email From is not authorized to send outbound e-mails to avoid SPAM. Ask your webmaster about this issue.

When you have the correct configuration data go to your Store Configuration and set that information.

Message: No items for home display

By default Comersus Cart shows two products per column with two rows in the home page. The number of rows may be changed from store configuration, pRowsShown key). So you are going to need at least four products defined as "Show in Home" to work properly. Maybe if you have made a bulk import you forgot to define products as Show In Home and then you get an error like this one. Consider also that sometimes this message appears because the cart can't read the DB.

Message: There are no payments/shipments in your DB

Comersus Cart needs at least one payment method and one shipment method to work properly.
Verify that you have one of each saved in your DB. To check that you can run these queries from the Generic SQL Tool
"Select * FROM payments" and "Select * FROM shipments"

Make sure also that your payment and shipping filters (like Quantity, Total, Weight) cover all the cases.
