Can't get plugins to work on vBulletin version 3.5.2

[slackovic]

When I install new plugin and set it's location (hook location) to be, i.e. forumhome_start, nothing is being displayed on the homepage of my forum.

I'm using plugin to display banners. It worked before (on vBulletin version 2.x), but now, after I upgraded vBulletin application to the version 3.5.2, nothing is being displayed on the pages where banners should be. When I delete all the plugins, everything works fine.

Even if I enter echo 'Hello'; nothing is being displayed...

I asked that question on vbulletin.com forum but they told me to try asking it here.

thanx in advance

Although you posted in the wrong place....

Do you have the plugin system turned on ? (I know a silly question but it is off by defult)

goto Admincp -> Vbulletin Options -> Plugin/Hook System

first of all, I'm sorry for posting in the wrong section... I checked if the plugin system is turned on and it is. so that's not the issue...

the plugin first gets information on which banner should be displayed and then it writes JavaScript code into the variable $bnr. I have put that variable into the template header but nothing is being displayed (I even checked the source code, but there is nothing at the place where I put the variable)
