Errors while updating the WPL plugin

While updating the WPL and any other WordPress plugins, you may be faced with error messages by WordPress such as "could not copy file ......." or "could not delete ...."

These errors are not related to WPL. In some cases, to fix these errors, you should delete the WPL plugin folder using the FTP or cPanel file manager.  To do this, connect to your website directories and delete the WPL plugin directory manually.  Then, try to update or install WPL again.
