Define Pages Editor Fatal Error

[DesignbyDemeter]

Greetings,

I'm down 3 days now with the page editor and need assistance. Was working fine for weeks, then when I was creating extra define pages, I wound up getting the following error when trying to click on Define Pages in Admin

"Fatal error: Cannot redeclare class base in /home/handmad/public_html/includes/classes/class.base.php on line 17"

I've never touched this file - I'm pretty lost and I've literally spent hours prior to asking for help.

Thank you in advance,
Laura

If you have never customized/changed the files in /admin reload the files as it sounds like something could be out of date ...

NOTE: it is always a good idea to back up your site before overwritting files ...

Which files would this be coming from - do I need to reload the entire admin dir?

Thanks,
Laura

(PS - Hope things dried out at home~)
