[Plugin: WordPress Form Manager] Registration unsuccessfull in 25% of submissions

Are you using a caching plugin? This would cause some submissions to be ignored, since they would be viewed as ‘duplicates’.

i am experiencing this same behavior on a form we are running at
https://www.ottawacitizenallstar.com/ultimateinsider

Funny thing is, i haven’t actually turned on WP Super Cache yet, though i understand from our host that SQUID is running with this server, so wonder if this could be part of the problem.

THey are looking into it currently.

Though i have to wonder why would a submission with different data be viewed as a duplicate. especially since i am just storing the data, not displaying it on a page or post or anything.

@hoffcamp,

We at AGX are responsible for the maintenance of the GentBC website mentioned in the above comment from jelleverspurten.

As we just reviewed the plugin, we noticed that the plugin throws a javascript error on page load in all browsers on line 143 of the following script: /wp-content/plugins/wordpress-form-manager/js/userscripts.js

While this might not be a severe error, some people running this page in IE might disable javascript when presented with this error, so perhaps this is what went wrong in the first place?

For the sake of clarity, the site is using W3 total cache and the form pages are not cached while we run our tests.

Could you please respond to this issue?

@hoffcamp,

We’ve been able to reproduce the problem jelleverspurten described by enabling the page cache in the W3 total cache plugin.

When trying to submit a form on a cached page, the user gets redirected to an empty form first, but after reloading and reposting the form the form gets submitted correctly. Offcourse this is not acceptable.

This is the first time we’ve encountered such a problem in combination with the W3 total cache plugin. After all, this plugin does not cache posted data, so there never should be any problem in the first place.

We generally use Contact Form 7 with our websites and never had any issue with it, just so you know.

Again, the GentBC website could really use some caching, so as long as this issue is not resolved, we can not enable caching on this website.

Could you please respond?

This is the problem with caching: a nonce is created for each form, and if the nonce expires before the cache is reloaded, then the nonce check will fail, and the submission is discarded. This is a ‘security feature’. I’ll add an option to disable the nonce checking and let you know when its posted.

For the Javascript, this is a bug. You have to check the ‘required’ option for any form item that can become required using conditions. This is okay, since the conditions will immediately hide the asterisk if the item is not required yet. The error is caused by there not being an ’em’ tag to show/hide.

@hoffcamp,

This would be really awesome. Thanks for the fast follow up.

I just posted the update.

I looked for the new setting, but could not find it. Could you point me in the right direction?

Sure:

Forms > Advanced Settings > Security (at the bottom)

Thanks! I’m an idiot. Just realized I was running one version too old (prior to the addition of this feature). I thought I was going crazy, not being to find it still. Thanks for your help and a great plugin!

I running into a problem where in updating the plugin, I get this error:

Unpacking the update…
Installing the latest version…
Removing the old version of the plugin…
Could not remove the old plugin.
Plugin update failed.

I’m assuming it is something wrong on my end and will search the broader WordPress forum. If you’ve seen this before and happen to know a solution, I’d be grateful for any help.

Yikes! I have no idea. Make sure you backup your database.

You could try a manual update. Just replace the files in wp-content/plugins/wordpress-form-manager with those from the latest version.
