Something is crashing them. What if you enable only one plugin, will it crash anyway? Can you list all non-default plugins you are using?

Also make sure you're using the latest stable version of [u]all[/u] plugins.

I used to have just the YouTube plugin and it crashed then, the addition of the avatars plugin has made no change on that score.

The plugins in question are [url=http://forums.b2evolution.net/viewtopic.php?p=75770]Avatars[/url] and [url=http://manual.b2evolution.net/Plugins/youtube_plugin]YouTube[/url]

Both are the most recent version

Thanks

You could try deleting the YouTube plugin and then reinstall it.

The one on your front page works though it seems to be in a div that there's no styling for "<div class="youtube center">" in your css

It usually renders in "<div class="video_block">"

Unfortunately, deleting & reinstalling the plugin didn't help..

One thing to add: Both of these plugins seem to get deactivated only when they're getting heavily-used: When there's a YouTube video on the front page, the plugin will deactivate daily. When only older posts have YouTube vids, it stays up no problem. Same with avatars: Only if a recent post gets lots of comments does it do a fade.

So it's not that they get deactivated daily all the time: They only get deactivated when they're in active use. Is there a "Disable plugins when they use more than n% of the CPU" type setting or something?
