Based on the information provided in your bug report, it appears you're encountering an error when trying to create a basic table using Backpack's DevTools. The specific error you're seeing is "Call to undefined function Backpack\DevTools\Generators\exec()". This suggests there might be an issue with the DevTools package or its dependencies.

Unfortunately, the knowledge sources provided don't contain specific information about this particular error. However, I can offer some general advice based on the information available:

1. First, ensure that you have the latest versions of Backpack and its packages installed. You're using Backpack CRUD 6.7.43 and DevTools 3.1.7, which are recent versions, but it's always good to check if there are any updates available Backpack Versions.

2. The error suggests that the exec() function is not available or recognized. This could be due to PHP's exec() function being disabled on your system for security reasons. You might want to check your PHP configuration to see if this function is enabled.

3. If the problem persists, you might want to try clearing your Laravel cache and config:

   php artisan config:clear
   php artisan cache:clear
   

4. If none of the above helps, it would be best to report this issue directly to the Backpack DevTools repository, as it seems to be a specific problem with that package.

5. As a workaround, you could try creating the table manually using Laravel migrations instead of relying on the DevTools for this particular task.

If the problem continues, I recommend reaching out to the Backpack community or support channels with the specific error message and steps to reproduce the issue. They would be better equipped to assist with this particular error that isn't covered in the provided knowledge sources.

Hello @frank-rachel

First try to check if exec work on your PHP, create a file with this

<?php
var_dump(function_exists('exec'));
?>

If is disabled, can you check in your php.ini if there is a line like this

disable_functions = exec,passthru,shell_exec,system

And delete exec from disable functions.

Let me know if that works for you.

Cheers.
