Fatal Error Msgs

Something new just started up for me.....just clicking on "Activity Directed at Me (Members Commenting, Favoriting Artwork or Featuring Artwork) and I'm getting:
"Fatal error: Allowed memory size of 26214400 bytes exhausted (tried to allocate 1153663 bytes) in /var/www/vhosts/fineartamerica.com/httpdocs/controlpanel/activity.html on line 16"

I've forwarded to Tech Support...

Happens about 3 out of 5 times....anyone else?

Using Google Chrome on OS X Yosemite 10.10.2
