Hi, I am trying to get math formula's to appear. First I got the following: Failed to parse (Missing texvc executable; please see math/README to configure.): \sqrt 9 = 3 then I compiled and installed the texvc executable. Now I get the following: Failed to parse (unknown error): \sqrt 9 = 3 The only change (other than copying the texvc executable to the /math/ dir) is to make the setting in LocalSettings.php to: $wgUseTeX = true; P.S. I am getting mediawiki hosted, so I don't have full run of the apache server, etc... Thanks. _________________________________________________________________ All-in-one security and maintenance for your PC.  Get a free 90-day trial! http://clk.atdmt.com/MSN/go/msnnkwlo0050000001msn/direct/01/?href=http://ww…
