Hi. I have everything with the demo working perfectly. I have MySQL installed, the DB and tables created and populated with demo data per the installation instructions, the user credentials are correct, the examples all work perfectly.
When I try to test anything non-demo, I hit a wall, unfortunately. I did the following:

• Created a new DB / Schema and Table in MySQL
• Changed config.php to use that DB with an admin account that has access to everything and all rights in all Schemas in MySQL
• Copied the index.php code into an index1.php file
• Changed $g->table = “clients”; to $g->table = “coins”; (it’s about coin collecting, and that’s the table name in the new DB / Schema referenced in the config.php file)
• Saved index1.php in the same directory as index.php
• Went to a browser, change the URL that just worked for index.php to index1.php
• The browser comes back with a 500 error:
  • The website cannot display the page
  • HTTP 500
  • Most likely causes:
  • •The website is under maintenance.
  • •The website has a programming error.

If I change the config.php back to the griddemo and then go back to index.php, it works like a charm. I can go back and forth with the two configs and reproduce the same results predictably. Never works for my DB / Table, always works for the demo when I change it back.
Thoughts?
Thanks!
