When I tried to access "Special:SecureHTMLInput" I get the following error message.
"Fatal error: Cannot redeclare wfsecurehtmlextension() in /home/wiki/public_html/w/includes/specials/SpecialSecureHTMLInput.php on line 45".

I also get an error and have crossed checked everything.
"Fatal error: Call to a member function addMessages() on a non-object in /home/content/42/4737242/html/wiki/extensions/SecureHTML/SecureHTML.php on line 52"
I get this error as well upgrading an pretty old version 1.8.4 and performing a Wiki move from current server to new server. Got everything running on new server but Upgrading fails with this error:
[root@wikit maintenance]# php update.php PHP Fatal error: Call to a member function addMessages() on a non-object in /var/www/html/mediawiki/extensions/SecureHTML.php on line 52
Were you able to resolve this? If so what did you do?
