I'm having a strange problem submitting a form through Selenium Webdriver's PhantomJS API. Upon clicking the submit button, the form gets validated (are the username and password too short, or blank, etc.), but it does not get ultimately submitted. That is, if I submit an invalid form, and check the screenshot, there are alert notifications. If I submit a valid form, nothing happens. The JS on the page is supposed to validate the form, then submit it, when the submit button is clicked.
A couple rule-outs. I've tried both .click() and .submit() on the submit button, which is a button element. I've also tried .submit() on the form itself and on an arbitrary element (like password) within the form, which Selenium allows.
In fact, the same code works just fine if I'm driving Firefox and not PhantomJS. I'd rather not switch over, though, as Firefox is slower and gives me unpredictable connection trouble.
My specs: I'm using Selenium version 1.43 with PhantomJS 1.98 via Python 2.7 on Ubuntu 14.04 LTS (GNU/Linux 3.17.1-elastic x86_64).
Code below. First is my Selenium code. Then the html for the form. Then the login.js source code from the site. What I think is happening in the js is that for some reason the invalidHandler from the .validate function is being run, but the submitHandler is not? Thanks in advance for your attention.
# enter username and password up here first
submitEl = self.find_element_by_css_selector("button[type='submit']")
submitEl.click()
self.save_screenshot('login_submission.png')
Edit2: "self" is a driver object that inherits from the Webdriver.PhantomJS class. Now the form html:
<form class="form-login" action="" name="login" method="POST">
<div class="errorHandler alert alert-danger no-display">
<i class="fa fa-remove-sign"></i> You have some form errors. Please check below.
</div>

Edit: fixed the title

The ERROR at the end is not part of my problem, but more of a bookend here. It occurs when the scraping algorithm looks for a link that's supposed to be on the page that shows up after logging in. Since we didn't successfully submit the login form, that link is naturally not present.
i'm not exactly certain which of my changes caused the breakthrough, but i can say i added the following code. edit: only two of these were new. removed one.
webdriver.DesiredCapabilities.PHANTOMJS["phantomjs.page.settings.localToRemoteUrlAccessEnabled"] = True
webdriver.DesiredCapabilities.PHANTOMJS["phantomjs.page.settings.browserConnectionEnabled"] = True
and i submitted the form itself, rather than clicking a button ( i had also tried this previously, prior to changing the above configs ).
formEl = self.find_element_by_css_selector("form[name='login']")
formEl.submit()
