It looks like a plugin conflict. It’s possible there’s a bug in our code that isn’t handling this condition. At this point, I think you want to use the www.ads-software.com community official Health Check & Troubleshooting plugin.

Please see https://docs.gravityforms.com/conflict-testing-using-health-check-plugin/
for more information.

I’d also like to see a system status report.
https://YOUR WORDPRESS DOMAIN NAME HERE/wp-admin/admin.php?page=gf_system_status

See the status report below. I installed that plugin you suggested and reactivated each one, one by one, including the theme. The error is still presenting itself. We have this site build on kind of a sandbox since it’s not live. Not sure if that’s causing issues.

Please see this link and let me know if you can implement any of the remediations. It’s interesting it also mentions Infusionsoft.

https://www.ads-software.com/support/topic/curl-error-2-easy-handle-already-used-in-multi-handle/

I’ll keep researching.

Please set the following settings TRUE in wp-config.php
WordPress Debug Mode & WordPress Debug Log
I’m assuming the GF Feed Addon was disabled at the time you ran the system settings log?

This is looking like the issue:

cURL Enabled: Yes (version 7.69.1)

I haven’t tested with this version. You should be able to downgrade. Please let me know if that’s an option.

See
https://www.ads-software.com/support/topic/form-suddenly-not-working-after-20-april-2020/

[EDIT]
My development machine uses curl 7.69

So that might not be it.

If I downgrade the version of cURL, is that a server-wide change? If so, I may ask for our host’s assistance in doing it just to be safe. I’ll let you know.

Thanks for your help so far in trying to debug this issue.

Yeah, it’s server wide. I’m not even sure it’ll fix the issue. You mentioned you’re working in a sandbox, so you can try it before deploying it to production.
I’d still like to see a debug log if you can get one.
Sorry about the problem. It’s not something I’ve seen before.

[EDIT]
There’s also this for more background.
https://github.com/guzzle/guzzle/issues/2617

XMLRPC.INC which implements the curl interface does not use guzzle

[EDIT]
Sorry, I just realized that you mean a sandbox WordPress site. If this is a managed service site, you might not be able to downgrade.

If downgrading isn’t possible, there is also the possibility of disabling HTTP keepalive service. It involves a code change to XMLRPC.INC It’s very easy to do:

Look for line 944 in /wp-content/plugins/infusionsoft-sdk/Infusionsoft/xmlrpc.inc

If it looks like
$this->keepalive = true;

change it to
$this->keepalive = false;

This change will resolve the issue, but it won’t hurt anything.

Thank you for your help. You’ll have to pardon my ignorance, but I’m not exactly sure what to follow in that thread you linked to.

Ok, I’ll give that a shot and let you know. Thanks!

Yeah, that guzzle thread was a bit thick. It was further evidence that libcurl has changed in some way.

BTW: the keepalive change MIGHT fix the issue.

It appears to have fixed it. I just received a new Contact within Infusionsoft. You have been a massive help and your customer support is kick ass. Thank you so so much.

I think I’ve confused the versions.

From
https://www.ads-software.com/support/topic/curl-error-2-easy-handle-already-used-in-multi-handle/

I turned the keep-alive back on, and the site continues to work. This may have coincided with our web host rolling back the cPanel cURL version. Turns out the cURL error began after a cPanel update where cURL went from version 7.69.1 to 7.79.1.

So rolling back in your case is NOT recommended

Yeah, I didn’t rollback. Your reply to a possible fix caught my eye before anything was done. Again, huge thank you!

Is this a GoDaddy site?
