Checkout Error Line 24

At the top of my pages is the following error.

Strict Standards : Declaration of Templater::display() should be compatible with Smarty::display($resource_name, $cache_id = NULL, $compile_id = NULL) in /home/synergygs/public_html/rw-leanstore/core/class.templater.php on line 24

If Continue is clicked on the Shipping step of checkout, there is an error. Please help if you can.

Hello

What version of the program and php?

Best regards
Robert

Please make sure that your CS-Cart version meets official requirements

The version is 2.2.5

And what php version do you use? I think, it should be 5.3 or lower for 2.2.5

That explains it, thank you. Their server bumped up to 5.6 and they cannot reverse the upgrade. Any ideas as far as keeping the site intact?

Make upgrade or hire someone to fix compatibility issues
