Latest update broke our sites

Hmmm. Let’s see if we can figure out the issue together.
Which version of WordPress are you using?
How exactly are you using the plugin… sidebar widget? shortcode? which settings?

Are you able to share a link to one of the sites that has the issue?
We will try and recreate the issue on our end. To do so, it would be helpful if you could share as much info as you can. Much appreciated, thank you. We’ll get a solution ASAP. In the meantime, you can downgrade to the previous version here:

It is the latest version of WordPress.

I cannot share a link to the sites. But the thing they all had in common was another plugin, which simply included something similar to the following lines:

if(function_exists('get_field')) {
$something = get_field('something', 'options');
}

As you can see that is using the plugin Advanced Custom Fields, which was also up to date and active.

Deactivating that plugin, or yours, fixed the issue. But that plugin is active on lots of sites with no issue, it’s only when it clashes with yours that is the problem.

ah ha… a clue!
so there seems to be a plugin conflict with Advanced Custom Fields. When both are activated the issue occurs, correct? We’ll investigate this and get back to you.
Thanks for the feedback and we apologize for any inconvenience this may have caused.

No, not a conflict with ACF. Only a conflict when ANOTHER plugin uses ACF’s “get_field” function inside it, along with your plugin.

is this other plugin published, or custom built?

Custom built

Still unable to recreate this issue on our end.
We have a small updated on GitHub, but we’ll need more time to first see if we can recreate the issue.
What version of PHP are the sites running, by the way?

Can you be more specific as to how your custom plugin is setup?

I have the same problem,
it creates a conflict with the plugin cooked, maybe you can use it to find the reason

Thank you Sandra! We can now recreate the issue and should have a solution for you to test in the next 30 mintues.

Update:
We might have resolved this issue. If you would be so kind, please install version 1.5.1b available from GitHub and let us know if this resolves the issue for you.

Thanks that version works ??

That’s splendid news.
We’ll do a bit more testing and push out the official 1.5.1 release later today.
A sincere thank-you for your feedback.

OK version 1.5.1 has been released here on WordPress. This issue should be resolved. Post back in this thread should you continue to experience this exact issue.

Works nice on my system, thank you again. ??

I hope Shaun Robinson’s problem is also solved.

The previous update broke my site, and the latest release (and the one on Github) also.

BTW why is the directory “anual” as opposed to “annual”?
