[gitHub Bug #1452] [vanilla 2.1]Getting a blank page on WhosOnline setting in dashboard

oldcai

I uploaded the plugin and changed the owner of all files to web server user (www-data), then get a blank page in the dashboard when setting whos online.

Then I got this article, but the cache folder and it's children are already writeable. Even if I chmod -R 777 cache/ sames not work anyway.

Then I enabled the "Debugger" plugin. Nothing changing.

So I read this article. Added $Configuration['Garden']['Errors']['MasterView'] = 'deverror.master.php'; to "conf/config.php", the setting page (/plugin/whosonline) still blank.

Then another try. I edited the "php.ini“ fiile, set
display_errors = On error_reporting = E_ALL & E_STRICT

Errors still not displayed and HTTP statue still "200".

Environment:
Nginx/1.2.4
PHP/5.3.17
Vanilla/2.1a26

Error Url:
/plugin/whosonline

Description:
page empty, but HTTP statue 200.

And another question by the way: How can I add "This discussion is related to the WhosOnline addon." to this post?

In the meantime, can you post a bug report on gitHub? Report the bug number here?

And another question by the way: How can I add "This discussion is related to the WhosOnline addon." to this post?

That is a really good question and I wish we could do that, but not at the moment. Noworries, 'WhosOnline' is in the title.

Have you tried checking the source files for instances of &$? These needs to be changed to $ instead. I don't remember the exact reason why as I'm no PHP developer but there are quite a few discussions related to this on the forums.

P.S.: Here's a related discussion: http://vanillaforums.org/discussion/comment/134464/#Comment_134464
...and another one with the explanation of why: http://vanillaforums.org/discussion/comment/154938/#Comment_154938

@UnderDog Thanks for your suggestion. I reported it to github #1452, but I'm not pretty sure does it help with these little information.

@kasperisager thanks a lot, but it sames that way couldn't fix this issue.

@kasperisager Please forgive me for my arbitrary.

I edit the "class.whosonlinemodule.php" file and get that conclusion, but the plugin maybe initiated in "default.php", and when I change it in your way in this file, it works.

Thanks again.

as mentioned for all 2.1 plugins.
