Hello,

I have added Enhanced Admin Grids (+ Editor) in my magento 1.9.1.1 version.But when I try to upload file it was showing this error-

SQLSTATE[42S02]: Base table or view not found: 1146 Table 'zotezo.customgrid_grid' doesn't exist, query was: SELECT main_table.* FROM customgrid_grid AS main_table WHERE (module_name = 'admin') AND (controller_name = 'index')
and admin was gone. What is the issue here?

Thanks, Dwaipayan
