I'm getting this error on www.gosportwx.com under my UV photo this was working yesterday.

Code: [Select]

Doing a view-source of your page shows

reloading your homepage with ?force=1 causes reload of the cache from temis.nl and now shows

and your page is ok again.

I think your site just experienced a timeout glitch trying to fetch the data from temis.nl for UV data and the empty cache file caused the Notice errata.

Hi Ken

I've been getting blank updates all of this week too, first time ever. I thought temis was down, but obviously not. I have turned on error checking and the only thing that pops up, is this:

Code: [Select]

Warning: count(): Parameter must be an array or an object that implements Countable in /home/wareham1/public_html/uv.php on line 38

Code: [Select]

for ($i=0;$i < count($UVfcstUVI); $i++) { ?>
Best.

So something is amiss between your webserver and temis.nl
A >2 second DNS lookup is suspicious.. definitely shouldn't take that long.

I'm getting 100% packet loss myself when I ping temis.

I have been seeing the UV timeout issue quite a bit over the last few weeks. It is not just your site. I have submitted a comment using their contact form: http://www.temis.nl/contact.php Others may want to do the same. (I am not sure if my contact post made it to them or not... it appears to have timed-out as well)

I received a reply from Ronald van der A this morning:

Hi Lauren,

We are aware of this problem and have it under investigation at this moment. The site works fine, but there
seems to be some issue with the network connection.
Hopefully we have the bandwidth completely restored soon!

Kind regards,
Ronald

Thank you for posting that info here.
