When I visited this site today I saw some horrible messages from the UK-tides WordPress plugin.
It appears that there is a problem with tidetimes.org.uk today – it produces no results for Chichester Harbour (Entrance) – which is the default for the
tideurl parameter of the [bw_tides] shortcode.
While visiting the tidetimes.org site I also noticed a number of locations which are actually closer.
First I saw that there was tidal information for Langstone Harbour
Then I realised that Northney is the nearest.
And there’s Bosham as well.. the location for which I originally wrote the plugin.
I should have seen this a while ago… when I updated the banner image last October!
