Be aware extension/mod based on vqmod/oocmod work by search code and change it. If code from default module/theme is different with your third party module/theme, that mean you need adjust it. For example, code default "abcde" and my extension need search code "abcde" and change it to "abcd". May be code "abcde" can't found on your module/theme, but there are "cdeab", so you need adjust code to find code "cdeab" and change it to "abcd".
