Conflict with Mailpoet

Carlen,

Sorry for not replying earlier. The problem is mailpoet. They use a thing called prototype.js which has a known conflict with jQuery. There is nothing I can do to fix this, the solutions require changes to your theme/wp installation:

Thank you for the reply. I’ll contact the other plugin author with this information.

The mailpoet authors said the issue is probably that your code loads scripts in all admin pages, not just the admin pages for your plugin. Is this a possible issue?

No.

Scripts are enqueued using the methods defined in the codex. Loading scripts only when required will lead to all sorts of complications.

The problem is prototype.js and how it is used by mailpoet. There is nothing I can do to the plugin to remove the conflict.

Hi Carlen
I have the same issue – for now I am disabling QPP while I do Newsletter editing -this is the only part of MailPoet that having QPP active effects.

I too had the same replies from aerin and MailPoet.

This is an unfortunate impasse. Two plugin authors saying the other is at fault.

I’ve managed to find a fix. It’s a bit of a hack to QPP but it does work. Here’s the download: https://quick-plugins.com/quick-paypal-payments/qpp-update/

If you could test and let me know that would be great.

As an aside, I had an email from MailPoet support saying they know about the jQuery conflict and their next version won’t use protytype.js

Closing this thread as the latest update fixes this issue
