[fw-core] Application-Session problem

I’m having a problem.

I was trying to destroy a session I was working with and I used a PHP native function ‘session_destroy’ in stead of the class method destroy.

Well I could have not predicted what was going to happen next. Across all my pages in my application I’m getting this warning.

Warning: Exception caught by form: Method form does not exist Stack Trace: #0 [internal function]: Zend_Form->__call('form', Array) #1 [internal function]: Schedule_Form->form(NULL, Array, 'render('

 

I have never seen this warning before, honestly I have no idea what is going on and why this warning would be shown.

I rebooted my server in terms of trouble shooting, there were no changes the warning persists.

 

Could some one explain to me what I did and how to fix it.

Thank you so much in advanced.
