急~安裝完模板後網頁出現Fatal error: Call to a member function Param() on a non-object in /home/nailshop/public_html/templates/shaper_maxima/index.php on line 22

下載來的板模檔案有4個資料夾
分別是 shaper_maxima_template_j2.5_j3.x.zip
shaper_maxima_quickstart_j3.x.zip
shaper_maxima_quickstart_2.5.zip
plg_system_helix_j25_j3.zip

我的安裝方法是把shaper_maxima_template_j2.5_j3.x.zip,這個檔案用後台安裝 出現Fatal error: Call to a member function Param() on a non-object in /home/nailshop/public_html/templates/shaper_maxima/index.php on line 22

第二種方法我也試過用ftp上傳解壓縮好的shaper_maxima_quickstart_j3.x.zip ,重新安裝joomlau,結果裡面沒有模組 ,一樣是原廠的那幾個模板

請問是哪個步驟錯了呢?Fatal error: Call to a member function Param() on a non-object in /home/nailshop/public_html/templates/shaper_maxima/index.php on line 22 到底要改哪裡呢?
