I'm using vB 4.2.3 PL 2, and I'm having both Extra Profile Fields Page and Extra Profile Fields Tab, but when the Tab product is enabled, it shows error on the header of profile member page:

Before this time, I've used this product with no error, but seems today it's showing error.

In the line 4602 functions.php:

trigger_error('fetch_template() calls should be replaced by the vB_Template class. Template name: ' . htmlspecialchars_uni($templatename), E_USER_WARNING);

and in line 599 member.php, it is:

($hook = vBulletinHook::fetch_hook('member_build_blocks_start')) ? eval($hook) : false;

What should I do? Any comments rather than disabling this product?

PHP version is 5.6.28
