Hi guys,

I've seen a rather large number of these errors in my event viewer the past few days. Any idea what might be causing them, or how I could even start to troubleshoot? Thanks!

Module Load Exception
Message: DotNetNuke.Services.Exceptions.ModuleLoadException: Object cannot be cast from DBNull to other types. ---> System.InvalidCastException: Object cannot be cast from DBNull to other types. at System.DBNull.System.IConvertible.ToBoolean(IFormatProvider provider) at System.Convert.ToBoolean(Object value) at Smith.DNN.Modules.ProductDetail.ProductMain.q() at Smith.DNN.Modules.ProductDetail.ProductMain.Page_Load(Object sender, EventArgs e) --- End of inner exception stack trace ---

Hi Alex,

Try taking the following steps to resolve this issue:

1. From the store admin menu, click on the page template button to go into the page template editor and delete all your page templates.

2. In file explorer, navigate to your \portals\[portalid]\smithcart\tenplates folder

3. Delete all the files in the \portals\[portalid]\smithcart\templates folder

4. Reset iis and restart the application from the dnn host menu

5. Go to product listing page and see if your products are displayed.


Hope this helps!

Hi Alex,

It's possible. I would recommend making a backup of your customized template then resave the default template to confirm if the issue is caused by your custom template.
