If you use WordPress and have tested some plugins and removed them later, it is possible that you have much waste tables still inside your database.
- First do Database Backup with MySQL DUMP
- Then check it enter the mysql console as your mysql admin user and do:
$mysql -u mysqladminusername -p
mysql > use databasename;
mysql > show tables;
System echo:
+---------------------------+ | Tables_in_wordpressdatab | +---------------------------+ | wp_commentmeta | | wp_comments | | wp_links | | wp_options | | wp_postmeta | | wp_posts | | wp_term_relationships | | wp_term_taxonomy | | wp_termmeta | | wp_terms | | wp_usermeta | | wp_users | +---------------------------+ 12 rows in set (0.00 sec)
If this default structure is seen the plugins tables are removed correctly.
If not do, delete waste tables with:
mysql > drop wp_old_plugin_table_name;
logout with „quit“ and test the WordPress Blog with logins and handling.
Remark: You never know what changes plugins inside your database do, the authors are unknown by yourself! Less is more secure!
