I have installed a mirror of Wikipedia in my site here : http://encyclopedia.meta99.com/ But i have some problems. I never used MediaWiki in past and i'm a newbie. Can you help me ?

1. Some pages has strange words that don't exists in Wikipedia- For example the "Cats" page and the "Dogs page" :

http://encyclopedia.meta99.com/wiki/Dogs http://encyclopedia.meta99.com/wiki/Cats

has strange words in the page :

{{#if:| [[{{{diversity_link}}}|Diversity]]}}
{{#if:| Binomial name {{{binomial}}}}}
{{#if:Felis silvestris catus| Trinomial name
Felis silvestris catus(Linnaeus, 1758)}}
{{#if:| Type Genus
{{{type_genus}}}}}
{{#if:| Type Species
{{{type_species}}}}}
{{#if:| [[image:{{{range_map}}}|200px|]]}}
{{#if:| {{{binomial2}}}}}
{{#if:| {{{trinomial2}}}}}
{{#if:| [[image:{{{range_map2}}}|200px|]]}}
{{#if:| {{{binomial3}}}}}
{{#if:| {{{trinomial3}}}}}
{{#if:| [[image:{{{range_map3}}}|200px|]]}}
{{#if:| {{{binomial4}}}}}
{{#if:| {{{trinomial4}}}}}
{{#if:| [[image:{{{range_map4}}}|200px|]]}}
{{#if:| {{{subdivision_ranks}}}}}
{{#if:|

Why these terrible words ? Exist a setting to disable the words in the output ?

2. I do not understand where is the system to change the output template/skin. I have changed some file in the directory /skins/ . For example the MonoBook.tpl but the output continue to be the same. If i change the directly the MonoBook.tpl file in the directory /skins/ why the output is identical ? A problem of cache ? I need ro change the html output to make it similar to my other pages different from MediaWiki. But i have failed to change the template. Why if i change directly MonoBook.tpl the output continue to be identical ?
