is_a is only suported from PHP 4.2 and up. Surprised this is actually used in code due to compatibility issues. If you are familiar with PHP you can try and rework the line to somtething to the extent of:
if(strtolower(get_class($<the_class_instance>)) != 'class_name_in_lowercase')


Otherwise you could try to upgrade to PHP >= 4.2

Why? PHP 4.2.0 is more than three years old time to move on.
I have updated the system requirements for XOOPS 2.2.x to say minimum 4.2.0, but this really should not be a surprise to anyone.

However, just to beat the rush: XOOPS 4 will be PHP 5 ONLY

Oh yes, wholeheartedly agree that it is time to leave compatibility with some older PHP versions. But naturally it should be noted in the installation requirements. It's just that I am so used to seeing the get_class type of syntax instead of is_a in the 2.0 kernel and core modules that I half expected that to have carried over to 2.2, which I haven't had much time to take an in depth look at unfortunately.
What other 4.2+ only functions are used in 2.2?
