Deprecated: Non-static method SpecialSecureHTML::trySubmit() should not be called statically in /web/wiki/includes/htmlform/HTMLForm.php on line 656
Any idea what's wrong ?
I get a similar warning every time Secure HTML is called:
Strict Standards: call_user_func_array() expects parameter 1 to be a valid callback, non-static method SecureHTML::secureHTMLRender() should not be called statically in /mediawiki/includes/parser/Parser.php on line 4279
