The maintenance settings tab allows you to make some maintenance operations that are not directly accessible elsewhere. This tab is visible only if Weather Station runs in extended mode.
Many views of the administration screens of the plugin may be customized by your activity or by checking/unchecking options in the Screen Options upper tab. If you want to restore these views to their defaults, just click on the corresponding button.
Forcing a refresh of the database
In some occasion, you might want to force a refreshing of all the data for all the stations. Click on the “Purge Only” button to truncate database tables and to wait for a scheduled resynchronization of the data, or click on the “Purge & Resynchronize” button to truncate database tables and to force an immediate resynchronization of the data.
If you choose “Purge Only” you may experiment blank stations details and data before the resynchronization is executed. For detail on potential delays, please read this.
