I installed the Admin Profiles plugin and updated all of the PHP scripts, as per the installation instructions. I double checked the changes I made, but the following error is still occuring:

1146 Table 'erezer_net_13.zen_pet_storeadmin_menu_headers' doesn't exist
in:
[SELECT id FROM zen_pet_storeadmin_menu_headers WHERE header = 'Configuration']
If you were entering information, press the BACK button in your browser and re-check the information you had entered to be sure you left no blank fields.

I searched the Internet, the support forum and this thread for an answer to this problem and I still cannot find an answer.

This thread is huge, so it could be cumbersome to read the entire thread to find an answer for this problem in the time I need it solved.
