Problems with database text field youtube

[MyPeSePe]

Good evening, I have a problem with my vbulletin forum. It turns out that I come from a migration of phpbb and the youtube bbcode are as follows: [youtube: 3ob99ona] ID0y11TzQ4g [/ youtube: 3ob99ona] and pass the command on the database to replace it [youtube] ID0y11TzQ4g [/ youtube] I do absolutely nothing

UPDATE vbpost SET pagetext = replace(pagetext,'[youtube%','[youtube');
