Java Script Error Ninja Forms

Hi,

Even with all minifying and combining settings OFF and after clearing the cache, the issue persists. However, if Litespeed is deactivated, it works immediately.

could you please try reset to default setting , and see if it works ?

Best regards,

Hi there,

I have reset the settings as you’ve suggested and will continue to monitor. As the issue doesn’t appear immediately, I’ll need to wait a day or two to see if the problem persists.

I’ll update the thread once I’ve been able to check this.

Thank you

Update – The issue has actually occurred almost immediately. The issue doesn’t occur when viewed as a logged in admin user. But if the page is viewed as a new user (incognito window) the issue persists.

The forms fail to load and the following error occurs in the dev console.

I would appreciate any assistance you can offer to rectify this.
I have once again deactivated Litespeed so that our users don’t experience the issue.

Thank you.

Hi,

Could you please explain me a bit for how can I reproduce this issue ?

1. install a WP

2. install https://www.ads-software.com/plugins/ninja-forms/

3. install LSCWP

4. enable these 2 plugins

5. set up a form in a page

6. the issue happens by then ?

Best regards,

Hi there,

Essentially yes. Although we have several Ninja Forms Add-ons also on the site.

We use the Salient theme.

We have carried out testing by disabling all plugins except the Ninja forms add-ons and Litespeed cache and the issue does persist.

I can activate Litespeed for a short time to allow you to see the issue on our site, but we would obviously have to co-ordinate this to ensure that it’s online for as little time as possible due to the disruption of not having our forms working on our customers.

Many thanks

Hi,

Please join our Slack

Hi there,

Unfortunately, while I do have a created Slack account I’m unable to join via the link you’ve shared above. Receiving a variety of errors from it expecting me to have a @litespeedtech.com email address to a URI mismatch when I try to sign in to my existing Google based account.

Can you please advise if there is an alternative way we can do this?

Many thanks

Hi,

May I know your e-mail ?

I can send you an invitation

Best regards,

Hi,

invitation sent.

Best regards,

Thank you. I’ve accepted the invitation and will message on there.

Would love to know what worked. Same issue on Cloudways with Breeze caching plugin. Theme Flatsome.

FIXED
I disabled Breeze’s “Lazy-Load images” feature and the form is working again. All other minification and grouping options are active.

Just for reference, I was having a similar issue in that the backend editing was throwing the same JS console error. The form on the front would load, but the CAPTCHA was not loading and not allowing the form to submit. I found that Ninja Forms was conflicting with Yoast SEO for some reason. As soon as I deactivated Yoast, I was able to edit the form and process a submission. Hope this helps someone.
