I tried to run WordPress 3.9 and BBQ together on an HHVM + nginx Server. The theme works perfectly under Apache, but with HHVM, some widgets (like Social Widget or Slider) doesn’t display on the frontend.

Example: http://gopeter.de/transfer/bbq-on-hhvm.png

Do you know whats wrong? I think this incompatibility isn’t that huge since the entire backend etc works fine.

Some additional informations:

I played around in the /includes/widgets/widget-social.php file and noticed, that the $nice_options variable is empty.

echo ‘###’;
print_r($nice_options);
echo ‘###’;

Returns: ######

Are there some troubles with globals?

Hello,

Thanks for writing.

I’m trying to visit the site you’ve sent us and I get: 504 Gateway Time-out – nginx/1.6.0

I’m sure these problems have to do with server configuration.

Best,
Juan.

Sorry, tried something out. Please check again 🙂

[Juanfra Aldasoro]

Well, I don’t know how is that nginx handle global variables. Check if you get something with print_r($GLOBALS);

The problem must be there, and then there’s a server configuration issue.

Best,
Juan

The `$GLOBALS` var is full of stuff (320.000 lines), but it seems that `nice_options` is empty but filled inside `wp_object_cache`. Should I attach the file?

[Juanfra Aldasoro]

Are you using any cache plugin?

[gopeter]

Not anymore. Anyhow, `wp_object_cache` is an offical WP class: http://codex.wordpress.org/Class_Reference/WP_Object_Cache

[Juanfra Aldasoro]

Thanks for your response. Yes, I am aware it is an official WP class.

My point here is that PHP, with your configuration, is not taking the global variables. At least $nice_options which is the one taking the data to make some modules work/or not. Like the social widget, or the slider.

Did you perform any other test with global variables on that server?

Juan.

Hi.
I just installed a new local virtual machine with HHVM + Apache and it works!
Now I wonder which nginx config does prevent global vars from working properly? I even tried the official nginx.conf from WordPress, but the global nice_options is always empty.

Do you have some ideas?

[gopeter]

Strange, but I figured it out: I just activated a standard theme and switched back to BBQ. Now it works.

[Juanfra Aldasoro]

Hi Peter,

It is quite strange actually. We are used to work over apache, so in general terms I’m afraid I don’t have too many ideas about this issue. I’m happy it is resolved, though.

Have a nice day,
Juan.
