Hey all,

I have just installed the Mobile Front End extension. But for some reason I am just pulling up a blank page on the Mobile side only. I have tried disabling all other plugins but it still would just show a blank page.

Here is the information about my setup: (PHP & NGINX errors will be displayed below setup information)

Errors:

PHP

NGINX

2014/01/16 17:05:47 [warn] 14031#0: *4305 a client request body is buffered to a temporary file /var/lib/nginx/tmp/client_body/0000000601, client: 69.198.41.161, server: XXXXXX.com, request: "POST /api.php HTTP/1.1", host: "betad.XXXXX.com", referrer: "http://betad.XXXXX.com/index.php?title=Category:Air_Canada&action=edit"

The missing function mb_convert_encoding indicates your PHP hasn't been compiled with mbstring support.

MediaWiki has had always support for not having mbstring enabled, but I have just found that 1.22 version has introduced a new regression in which mbstring is now required. Enabling mbstring may solve the issue. I'll file a bug about that when bugzilla comes up again.

The first error is a memory issue. You should make sure if it's really happening with mobile frontend or the normal MediaWiki.
