Warning: Invalid argument supplied – Installed, Reinstalled, still error.

What contact form are you using?

Hi, thanks!
I’m using contact form 7, which works – BUT: The built-in contact form for ‘wp landing pages’ wasn’t working… that’s what sent me down this rabbit trail.
I’m at https://www.treeservicehendersonville.com, that’s the landing page…

You have javascript errors breaking our forms from

Uncaught TypeError: Cannot read property ‘left’ of undefined script.js?ver=3.7.1:316
Uncaught TypeError: Cannot read property ‘left’ of undefined script.js?ver=3.7.1:316

https://fullerlandandtree.com/wp-content/themes/FLTv17/script.js?ver=3.7.1

Fix your theme and these issues will go away.

I’ve installed it on other sites – both with theme ‘twenty thirteen’ theme, the basic one included in all wordpress installs… still the same error. they’re all on the same server, perhaps – is there some php version or some such making the error?

Send me links to the other sites and I will take a look

The JS error is breaking our form ajax for sure on the link you posted above.

Here is the other page: https://www.techguyasheville.com/go/testing/
It appears to work.
If you look at this screenshot, you’ll see the preview doesn’t load:

So I was under the impression the whole thing was not working.
Although, you’ll also see that on this site, the same error is there on this screenshot:
https://dl.dropboxusercontent.com/u/21402424/Screenshot%202013-11-08%2010.41.45.png

So the plugin works on https://www.techguyasheville.com then?

The previews are pulled from mshots a wordpress 3rd party service. We dont have any conrtols over that.

The error goes away when you change line 466 of module.global-settings.php
From the original:
foreach ($custom_fields as $field) {

To this:
foreach ((array)$custom_fields as $field) {

DavidWells — is this an appropriate change?

The error:

Warning: Invalid argument supplied for foreach() in /home/content/28/11710228/html/wp-content/plugins/landing-pages/modules/module.global-settings.php on line 466

has been solved on our dev branch https://github.com/inboundnow/landing-pages/commit/305a0f2e64a1ba986c12e802807eedc1dbf587c0

It will be released in a day or two

Thanks for for suggestion greg!
