[Mediawiki-l] Saving changes to Main Page results in blank screen

[Chris Braster]

I just recently upgraded from 1.6.3 to 1.6.5.  Since the upgrade only  
one user account (1st non-admin account ever generated) can make  
changes to the Main Page and save it with no issues.  If any of the  
other accounts, or even the admin account, try to do so, when they  
click the save page button, they get a blank page and the save  
doesn't take.  All accounts can edit all other pages fine with no  
issues.  It is just the Main Page that won't allow any saves, except  
for that once account.  Any ideas?

Thanks,
Chris
