@mojolazarus it looks like the xml expected by that code is not well formed. I mean, it's almost sure that the problem is not in your b2evolution but in the external server that it is trying to connect with.

Is that block loading a third-party plugin ?
What video provider is it trying to connect with (youtube, vimeo, etc) ?

Maybe you should also investigate if your hosting provider performed an update in the server.

Thanks a lot for the reply mgsolipa. I have now realised that the problem is not restricted to the homepage but is all over the website. The code is the workaround that you helped me with to pull video thumbs from YouTube and Vimeo. The thread is below:

Any idea why it should suddenly stop working? I can check host gator for an update in their server. Is that an update in xml?
Thanks a lot.

All right, I didn't remember what I have done there. Thanks for the link to the other post.

The problem is dead simple: the script to get details of each video from Youtube that I quickly found and sent to you at that moment (http://snipplr.com/view/58573/), is based on the Youtube API v2, which is no longer available.

I updated the other post with a fix, please test it and let me know how it goes.

Thanks.

OK thank you. I have pasted the code for step 2 but received this error:
Fatal error: Cannot call method self::vimeo_apicall() or method does not exist in /home1/mogator/public_html/skins/chileno/_skin.class.php on line 126

Something I have missed I expect?

Thanks.

It doesn't make any sense, those are just a few calls to methods in the same class and, in worst case scenario, it shouldn't return a fatal error.

What version of PHP are you running?
Are you sure that you completely removed the old code and replace it by the new one?

Please try replacing line 55

if( $data = call_user_func('self::'.$matches[1].'_apicall', $matches[2]) )

with:

if( $data = call_user_func(array('self',$matches[1].'_apicall'), $matches[2]) )

Nice one mgsolipa, that works now! That is, replacing the php as described above did the trick. Just out of interest, why does specifying an array make a difference? Cheers.
