wp_PO_plugins Table Not Showing in phpMyAdmin

That sounds like an issue with your database server. Run this command in your sql window to build the table and let me know if you get any errors.

CREATE TABLE wp_PO_plugins (
			post_id bigint(20) unsigned NOT NULL,
			permalink longtext NOT NULL,
			permalink_hash varchar(32) NOT NULL default '',
			permalink_hash_args varchar(32) NOT NULL default '',
			post_type varchar(20) NOT NULL default '',
			status varchar(20) NOT NULL default 'publish',
			secure int(1) NOT NULL default 0,
			children int(1) NOT NULL default 0,
			disabled_plugins longtext NOT NULL,
			enabled_plugins longtext NOT NULL,
			disabled_mobile_plugins longtext NOT NULL,
			enabled_mobile_plugins longtext NOT NULL,
			disabled_groups longtext NOT NULL,
			enabled_groups longtext NOT NULL,
			disabled_mobile_groups longtext NOT NULL,
			enabled_mobile_groups longtext NOT NULL,
			PRIMARY KEY PO_post_id (post_id),
			KEY PO_permalink_hash (permalink_hash),
			KEY PO_permalink_hash_args (permalink_hash_args)
			);

#1005 – Can’t create table ‘mikeshup_wrdp1.wp_PO_plugins’ (errno: -1)

Here is a page describing that error. https://stackoverflow.com/questions/15152857/mysql-error-code-1005-errno-1

Try deleting the table before running the create table statement I sent you.

Support admin at webhosting provider suggested for me to try different engine by adding ENGINE=MyISAM to end of the above CREATE TABLE command; that looks like it worked, and plug-in seems to be working now as expected, thanks.

what is wp_PO_plugin ?

The table that holds the information stored for all posts.
