Just trying to index my site after installing the Relevanssi search plugin and got this error:
Fatal error: Class 'CRED_Form_Builder_Helper' not found in /nas/wp/www/staging/vss/wp-content/plugins/cred-frontend-editor/classes/Form_Builder.php on line 169
All seems ok after deactivating CRED – can build index, reactivate cred and all works but when indexing again the error is repeated.
Many thanks
Chris
