Fatal Error

[3blake7]

I have latest MW, SMW, and SF

When I enable SS, I can create signup form, goto page while logged in but I get error on page while anon. It's really read, the error message refers to other extensions, which I comment out and just get another error with another extension. If I unset the form variable, it goes away.

First it's Fatal error: Call to a member function isAllowed() on a non-object in for AdminLinks
Fatal error: Call to a member function isAnon() on a non-object in for LiquidThreads

Please help, thanks!

@yaronkoren any idea?

Means exactly what? (Version numbers would be nice)

Fatal error: Call to a member function isAnon() on a non-object in for LiquidThreads

This isn't really sufficient to make any guess on what is going wrong. Please have a look at [0] to provide a full stack trace. That said, given the mentioned isAnon/ isAllowed may refer to User::isAllowed / User::isAnon but this is just a conjecture.

MW 1.25.1 SMW 2.2.1 SF 3.2 SS 1.0

It only happened when logged out on Special:SemanticSignup

@mwjames all those settings made no difference, no stack trace or anything came up

I also sometimes get a proxy error, but only on that page and not every time.

The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /index.php/Special:SemanticSignup.

Reason: Error reading from remote server

If you have settings like below you should have some kind of trace for the fatal/exception either in MW or PHP log.

error_reporting(E_STRICT|E_ALL);
ini_set("display_errors", 1);
$wgShowExceptionDetails = true;
$wgDevelopmentWarnings = false;
$wgShowSQLErrors = true;
$wgDebugDumpSql  = false;
$wgShowDBErrorBacktrace = true;

Without a trace it is impossible to narrow down the issue and yet let alone to propose a fix (well I'm guessing something changed in 1.25 which makes Special:SemanticSignup going rogue).

The stack trace just isn't coming up, even with those settings. Sorry I can't provide more. It's really weird.
