canvas

I noticed that other people have had problems using the Canvas plug-in. I just installed it and I’m getting this error:

Warning: domdocument() expects at least 1 parameter, 0 given in /home/iloveswe/public_html/wp-content/plugins/Canvas/canvas-core.php on line 90

Fatal error: Call to undefined function: loadhtml() in /home/iloveswe/public_html/wp-content/plugins/Canvas/canvas-core.php on line 91

Has anyone else faced this issue? I have no idea what to do to get around this.
