Fatal Error after adding category to custom form
What do I need to change on line 155 to add another category to a custom form?
Fatal error: Cannot increment/decrement overloaded objects nor string offsets in /home/abc/public_html/
wp-content/themes/vantage/includes/custom-forms/form-builder.php on line 155
(I am not updating until the February maintenance update and authorize.net plugin with recurring payments is available - I just need a quick fix until then).
