Morning Stefano

I always hate saying this but am afraid I am going to have to… if things work and then suddenly stop working as they were then something simply must have changed. It can be a tweak to your WordPress theme… and update to ANY WP plugin…. a new WP plugin made active. It has to be something.?

Morning Andy.

I agree completely!

The only thing I have updated is Jetpack. I switched it off but it still doesn’t work…

Mmm. JetPack can cause an absolute riot of problems.
So – can I have a link so I can see this event?

Thank you Andy!

I sent you a PM with the login, as the forum is for members only. You are admin for both the site and the forum.

Something is screwing up all – well mostly all – of the javascript ‘script’ tags. Looks like you have turned on something to try and optimise them but is, in fact, making some of them invalid.

I do not know what that something is bit this is something new and a change…

You also appear to be running the forum page using w3-total-cache. That wont work proper;y as w3-tital-cache can not handle dynamically created pages which a forum naturally is. You need to exclude the forum page from ALL caches. Actually this might be the source of the scripting mess as well come to think of it.

Additional. I just noticed that your page is still loading stuff from JetPack so it it not fully deactivated. It’s an insidious plugin that can cause all kinds of hidden problems… This may, possibly, have something to do with things as well.

Andy, I deactivated and removed Jetpack completely. 

I looked at W3 Total Cache and the page /forum/ is there, not to be cached, as it was before.

But it still doesn’t work…

Odd. If you look at the source being generated you will see this displayed at the end of the HTML:

<!– Performance optimized by W3 Total Cache. Learn more: http://www.w3-edge.com/wordpress-plugins/

Minified using xcache (Request URI is rejected)
Page Caching using xcache (Requested URI is rejected)

Object Caching 7779/8126 objects using xcache

It also says it is ‘minifying’ it so that suggests the forum page is also not excluded frm the script minification option in w3-total-cache.

I am also seeing a LOT of scripts being loaded with a syntactically incorrect ‘defer’ statement at the end – like this:

<script type='text/javascript' src='http://www.irsa-stringers.com/wp-content/plugins/contact-form-7/includes/js/scripts.js' defer '></script>

I think the script is still being loaded but it could well be having a negative effect along the way.

I am not sure about the use of xcache. Not an expert there…

actually, with exception of the object cache, the caching is disabled (uri rejected)…  and the object cache (whether xcache, memcache or other) should be fine…

but dont think I have link to site to look further…

I tried to switch off everything but it still doesn’t work…

Recently, I only updated a couple of plugins like Download Manager and something else, nothing strange, and the WP theme.

I’ve had the same plugins for over 4 years and this thing never happened before…

Anything can be ‘strange’ if there is a conflict of some sort. It’s that new and updated stuff that is exactly what needs to be checked. You just need to deactivate them briefly to try things. Empty browser caches before each try.

There are a couple of other things I notice about your site that I am pretty sure I have not seen before. The first is that you are now using something that loads the ‘bootstrap’ library. This normally only has a minor inconvenience and we have developed code in there that tries to deal with it but… it is not a WP supported library and does conflict with the jQuery UI library – which IS supported. And the popup dialog we use is a part of the UI library. So – again – I have no idea of this might be responsible bit it is worth deactivating the component that is loading it. And that, I believe, is this ‘js-ticket’ plugin.

Which nicely brings me to the other thing as I do not believe that support ticket plugin is something I have seen before on your site. So I would start with this.

Andy, the problem is related to the theme!

I activated Twenty Twelve and everything was working just fine.

I just noticed, on the themes page (in admin) at the top, there is an error/message coming up:

Error : Please fix your theme to make plugins work correctly: Go to the Theme Editor and insert <;?php wp_head();> just before the line of your theme’s header.php file.

I did, but it still doesn’t work….

I need to contact those guys.

Thank you very much for your help! 

Curious. I saw no evidence that this was not being called. Donlt know what generates that error message either for that matter.

But

<;?php wp_head();>

is NOT the right syntax for this. It should be:

<?php wp_head(); ?>

Like that. try that instead.

Nothing, Andy…

I talked to the boys at Customizr (my theme) and they don’t know either…

They suggested to switch off some image functions but it still doesn’t work.

I don’t know what to do at this point…
