is wiki css broken?

Jump to navigation Jump to search

I have a theory about the root cause of the problem, but I need more data to confirm.

Can someone experiencing this issue please open the browser console (F12 -> Console tab), and post the contents of it? Also, which browser are you using?

If I my idea is right, you should see Uncaught ReferenceError: jQuery is not defined.

Same here. That's why I suspect the cause is js resources. However this issue seems to happen some time, and disappear some time. Maybe browser caches that once it successfully loads.

I see something else in Firefox:

SyntaxError: illegal character load.php:1:190

When I go to

view-source:http://robowiki.net/w/load.php?debug=false&lang=en&modules=jquery%2Cmediawiki&only=scripts&skin=monobook&version=20140108T004349Z

After character 190 it is a bunch of strange characters. I guess something was corrupted on the database?

It seems there are two separate problems then.

Everyone who sees Uncaught SyntaxError: Invalid or unexpected token is:

  • Using Monobook (the default skin), either by choice or by not being logged in.
  • Experiencing this problem continuously.
  • The root cause is that this script, which should contain jQuery and MediaWiki frontend code, has parts of it overwritten with 155648 0x00 bytes.
  • Because that script does not parse, the loading process is broken.
  • This probably requires a server-side fix.
  • People seeing this: Skilgannon

Meanwhile, everyone who sees Uncaught ReferenceError: jQuery is not defined is:

  • Using the Vector skin.
  • Using Chrome.
  • Experiencing this problem intermittently.
  • For the Vector skin, this script, which contains jQuery and MediaWiki frontend code, it perfectly fine.
  • However, that script is loaded by this script through document.write() of a <script> tag.
  • Chrome is known to block the use of document.write() to load scripts on slow Internet connections.
  • Thus, since the script that contains and exposes jQuery is not loaded, other code that depends on it errors with Uncaught ReferenceError: jQuery is not defined.
  • Possible fix: Go to chrome://flags, set "Block scripts loaded via document.write" to "Disabled", and restart your browser.
