Formstack JavaScript Error

Hi,

There is an issue with the formstack plugin when using Advanced Custom Fields within a WordPress site. Advanced Custom Fields is a very widely used page builder tool so we’d assume this issue comes up a lot.

When using the Advanced Custom Fields WYSIWYG editor field, the formstack plugin throws an error message. This only occurs on special pages (options, author pages, menu pages) – sections in WordPress that wouldn’t typically have WYSIWYG editor fields present.

We’ve developed a fix to at least not throw the large red error banners, but ideally the plugin would work in those locations as well.

The user displayed error is:
Failed to initialize plugin: Formstack.

The JS error that is shown in the console is:
Failed to initialize plugin: formstack ReferenceError: formstack_tinymce is not defined

We have implemented a fix on our version of the plugin which is to this file:
/wp-content/plugins/formstack/tinymce/plugin.js

The fix is to add this code after line 2 in that JS file:
if (typeof formstack_tinymce == ‘undefined’) {
return;
}

Often when the formstack plugin is updated it overwrites our changes so it would be great if you would consider updating the plugin.

Thanks for your help!!

Joe
