[Semediawiki-user] VERY frustrating error

[Alex M. H. <ont...@on...>]

This is the first time I am encountering this error, but after  
reinstalling SMW (I had patched it to try to use HaloACL, but that did not  
work; I deleted, recopied from the original SMW1.4.3 archive, then applied  
the Halo-only patch for SMW 1.4.3 and MW 1.15.1) everything seems to work  
properly except that I cannot see the icons at the tops of the columns on  
query printout charts.

I have double (and triple) checked that permissions are 755 for  
extensions/SemanticMediaWiki; I even did a chmod -R  
extensions/SemanticMediaWiki. I re-ran SMW_setup.php and  
SMW_refreshData.php.

I have quit and restarted the browser; I have quit and restarted Apache, I  
have even quit and rebooted the computer, all to no avail. My apache  
aliases are properly configured as well.

SMW works perfectly well on other installations on the same machine using  
the same extensions.

I am at a complete loss...

Any suggestions?

Thanks,
Alex
