Hi. Several of our members have reported this error: CALL TO UNDEFINED METHOD FIELDSHELPER::EXTRACT()6.5
after we upgraded joomla from 3.6.5 to 3.7 yesterday.
As far as I've been told it only appears in the EasySocial part of our website. The error will disappear when they reload, but some users are getting it several times.

(I cleared the cache in administrator after the upgrade.)
Do you have any idea as to what can be causing this?
May i know how to reproduce this error on your site?

Is it possible update your FTP access as well in case we need to troubleshoot this issue?

Hi Arlex!

I have not been able to reproduce it myself.
I did clear my browser's cache after the upgrade, so I don't know if it can be cache issue. If so, is there a way to fix this without having to tell all our users to clear their history (not something we would want to do)

Currently we do not have encounter this issue before so that was difficult for us to know how to prevent this.


FieldsHelper::extract();

I did do a global search from our component core file, it seems like we didn't have call this method, it might be something else 3rd party plugin or Joomla somewhere calling this method but your Joomla root core file do not have this method.

Perhaps you can check from your site and see is it have this file?
JoomlaFolder/administrator/components/com_fields/helpers/fields.php

Then open it check and see whether got this method?


	public static function extract($contextString, $item = null)
