Fatal error: Call to undefined function fetch_tag_list() (showthread, private message
 

Hello,

I didn't do any modifications on my forum. Currently, it's using (vBulletin 3.8.4 Patch Level 2).

When I go to single thread view (showthread.php), I got this error:

Code:
Fatal error: Call to undefined function fetch_tag_list() in /home/XXXXXX/public_html/showthread.php on line 1046
Also, when I want to read a private message, also got this error:

Code:
Fatal error: Call to undefined function fetch_tag_list() in /home/XXXXXXXX/public_html/private.php on line 1527
Anyone having ideas to solve this issue? :(
