I tried to install the SemanticMediaWiki extension v0.6 (current) on 1.9.0 and got the same symptom as I reported with a vanilla installation of 1.8.2 in the thread Empty pages..., ie just HTML head and body tags with no content.

From our prior experience, (partially) empty pages often result from PHP running out of memory (which, in this case, is not really SMW-specific). Try to set """ini_set( 'memory_limit', '20M' );""" in your LocalSettings.php.

Rob Church advised in that thread to try setting $wgDisableCounters = true; so I tried that in this situation, despite the fact that what that was intended to work-around was supposedly fixed in 1.9.0. But I got a result: with that in place I got the error message:

Fatal error: Class 'SMW_LanguageEn' not found in C:\Domains\intersp.org\wwwroot\extensions\SemanticMediaWiki\includes\SMW_Gl obalFunctions.php on line 136

Said class is defined in a file that is included at run-time (depending on your language setting). The "missing" class is included at runtime just a few lines before the problematic line 136 -- maybe the inclusion fails due to memory problems. Otherwise, you can check whether your file <SMW>/languages/SMW_LanguageEn.php is in a healthy condition.

Good luck.

I've gone over the semediawiki installation instructions several times and I'm sure I've done everything correctly. I haven't yet looked for any more appropriate forum to report this problem, but I thought that people here might be interested in what it took to get that error message. Here's the MW installation report again (for 1.8.2), let me know if any other info would help:
