WPMU Dashboard Plugin Error Message

Hello,

I just purchased a subscription and tried to download the dashboard plugin to one of my Wordpress websites.

I received an error message: Fatal error: Allowed memory size of 41943040 bytes exhausted (tried to allocate 323109 bytes) in /hermes/bosnaweb18a/b1272/nf.cphlinc/public_html/itstwist.com/wp-includes/functions.php on line 345

I had to remove the plugin to get the site to work again. My site is hosted on Netfirms.com - is there something incompatible with the plugin and my hosting site - or perhaps another plugin I have?

Thank you,

Caroline
