Error message - Strict Standards:Only variables...

Hi, I've installed Hot Host (joomla 2.5) template on my local computer (using XAMPP version 1.8.1)and followed your fresh "HOT Start Installation method". But Hot Joomla Carousel pro, Hot Spinner and Hot Joomla Gallary none of those extensions are working. On the home page just right top of the "Hot Joomla Carousel pro" module it shows following error. Not just home page those error messages are on all those extension page.
Could you please assist me to solve those problem. Thanks.

taht are just warnings , just level down error reporting level in joomla global configuration

Thanks Ivan you are great!
Just to let other people know (if they encounter similar problem) how I've fixed it -

Log in to the Back end --> Site --> Global Configuration --> Server --> Under Server setting area you will see "Error Reporting" drop down list --> from the drop down select "none" --> Save and Close and that fixed my problem.

My "Hot Spinner" extension also wasn't working I mean it wasn't displaying anything, no image nor animation. Here, how I've fixed that problem --
From the back end -
Extension --> Module Manager --> Click on "HOT Spinner" module --> Script Setting --> Image Encoding --> set it to "Enabled" --> Save and Close.
