Hello,

when i test my forum page by 'Google Page Speed', i got in report "Combine external JavaScript"
and these 4 files must be combine :
1- yahoo-dom-event.js
2- connection-min.js
3- vbulletin_global.js
4- vbulletin_menu.js

i used this mod "Combine It" https://vborg.vbsupport.ru/showthread.php?t=229530 , this is work but i got more problem like, when i login to profile for members the TABs not work, also quick replay doesn't work. so what's the best way or solution can i use for combine these 4 files javascript without any problem in my forum.

thank you advance.

I think those files are compressed, I don't think combining them is a good idea.
