Thanks for the hints. I raised the memory limits, checked the logs; but no clue. The server error log has no significant error messages. Some more info for all- even if I enable the SMW_Settings.php in LocalSettings, there is no problem. I get a blank page only when I add the enableSemantics('localhost'); line to the LocalSettings.php (SMW works only with this line). So it seems some problem with this function....?

*Really* blank pages (not even errors) sometimes occur when PHP runs out of memory, e.g. when loading a larger extension. Find "memory_limit" in your LocalSetings.php, and remove the comment signs from that line. Try experimenting with higher values. More than 100M, however, is most unlikely to be required.
If this fails, we will need a more thorough analysis.

Markus

Thanks Jim. Yes, the error reporting is off and that's not under my capacity to change that. But I added
ini_set( 'display_errors', 1 ); error_reporting( E_ALL ); to LocalSettings.php as hinted by Rob in an old post. But nothing is displayed yet :(

A blank page typically occurs when PHP's error reporting is turned off. The first thing I'd suggest is figuring out how to enable error reporting so you can see what's really going on. I believe this is done in the php.ini file.

Do you have access to the error log of your subdomain? If you have, you'll be able to see the error there.

This function just loads all the rest of SMW. Since I have no clue what could have caused the problem (we run SMW on many Linux machines without problems), I would suggest you to wait for two more days when we plan to make a first pre-release of SMW1.0 available. It's much better than 0.7 anyway ;)
Let's see whether the error persists there.

Don't know if this is related, but did a clean install of MW 1.11.0. Added SMW 0.7 as first extension. Set $wgDBuser/$wgDBpassword to root account in LocalSettings.php
When click Initialize button on Special:SMWAdmin, receive following error:
Database error A database query syntax error has occurred. This may indicate a bug in the software. The last attempted database query was:
(SQL query hidden)
from within function "SMW::setupDatabase". MySQL returned error "1064: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '-gen.`smw_relations` ( subject_id INT(8) UNSIGNED NOT NULL, su' at line 1 (localhost)".

Figured out problem/solution to my issue. The mediawiki database name contained a hyphen '-' wikidb-gen
Mediawiki does a clean install and seems to work fine. Semantic Mediawiki will not initialize.

Thanks for the report. I filed this as bug 11704 and gave it a high priority. If it persists in SMW1.0 (you can try SMW1.0-RC1, released recently), then we will address it before releasing 1.0 final.
