Hi,
I have been using that hack
https://vborg.vbsupport.ru/showthread.php?t=130887 it's work on my vBulletin 3.7.1 version. I do not have any problem. It makes hide all the messages but I have added a button to the Text Editor. Then I am choosing the message/link which I have to do it hide and then clicking the button that I made but adding 2 hide code. You can see below the example ;
Can you tell me how can I solve the problem ?
