after creating a module using the module builder and generating the folder is created, however the module does not appear to be available?
If you created the module with the code-behind files, then you will need to rebuild the project to enable the module. If you selected the non code-behind approach, then you should be able to enable the project by clicking the Reload link on the Admin page.
the module was created without code behind, after restarting the new module still does not appear in module list?
how do I rebuild?
If you did not use the code-behind, then there is no need to rebuild.
The module not appearing in the list suggests an issue with the SQL not getting executed.
How can we initiate the SQL or troubleshoot further?
