[Plugin: Custom Post Type Archives] Fatal error: Cannot redeclare is_post_type_archive()

Getting the same issue. NO idea how to fix it. Guess we should have looked at compatability before upgrading!

This should be fixed on the v1.5 which should be available in the next few minutes.

Please note that function ‘is_post_type_archive’ is renamed to ‘pta_is_post_type_archive’ so if you use it in your theme then you should change those function calls to call the correct function, because WordPress’s built in function won’t work with this plugin (it won’t return expected results).
