Making Themes compatible for 2.0.x and 2.1.x at same Time

Thx for so many answers :-). But i found the solution:

'<?php if (($wp_version < "2.1")) {
wp_list_cats('sort_column=name&optioncount=1');
}
if (($wp_version >= "2.1")) {
wp_list_categories('sort_column=name&show_count=1&title_li');
} ?>'

ooo..cool! Good idea ??

First time I’ve seen this thread.

Probably could use the function call if_function_exists(‘function_name’) as well. I think that’s it.

@drmike,

thank you for the answer. it works.
