The error is the official version of wordpress.

To fix temporarily while they do not, do the following:

Go to the folder

/wp-admin/includes

Open the file update.php

change the line 289 of that here:

printf( __( 'There is a new version of %1$s available. <a href="%2$s" title="%3$s">View version %4$s details</a> or <a href="%5$s">update now</a>.' ), $plugin_name, esc_url( $details_url ), esc_attr( $plugin_name ), $r->new_version, wp_nonce_url( self_admin_url( 'update.php?action=upgrade-plugin&plugin=' ) . $file, 'upgrade-plugin_' . $file ) );

for it here:

printf( __( 'There is a new version of %1$s available. <a href="%2$s" title="%3$s">View version %4$s details</a>.' ), $plugin_name, esc_url( $details_url ), esc_attr( $plugin_name ), $r->new_version, wp_nonce_url( self_admin_url( 'update.php?action=upgrade-plugin&plugin=' ) . $file, 'upgrade-plugin_' . $file ) );

Save the file and test the plugins page that will back up and running
