There is a bug in this plugin (Version 3.3.3), wich causes this plugin to fire 3 SQL updates for the
wp_postmetadatabase table on each page request. The problem is caused by the function
maybe_upgrade(). These update queries are fired on both frontend and admin interface.
CWS_PageLinksTo->maybe_upgrade() - Line 283 wp-content\plugins\page-links-to\classes\plugin.php
maybe_upgrade() is a migration function. The function searches for wp_options key “txfx_plt_schema_version” in a condition, which is unfortunately never set to the wp_options table after the successful migration. (See get_option(self::VERSION_KEY))
Because of this, each and every request on every page generates
wp_postmetaSQL updates in the database, because the plugin tries to migrate data.
These queries look like this:
