We suspect the plugin failed to create a table, or table was corrupted.
Let’s try this solution with the database by following these steps to resolve the problem:
Deactivate and delete the Print Manager Plugin from WordPress
Access the Database
Drop and delete the entry ‘zprint_tables’ field from the wp_options table
Drop and delete the table zp_locations (If it exist in the database)
After the table ‘zp_locations’ and zprint_tables field are dropped from the database.
Now install and activate Print Manager plugin again from www.ads-software.com
These steps will remove any existing fields from the database blocking the tables from being created. On the next activation the tables should be created as a clean install.
