"Sorry, your request cannot be processed." on Additional Payment Methods install

[Jeff]

Hi,

I’m trying to install the Additional Payment Methods plugin and am receiving this error:
“Sorry, your request cannot be processed.” upon selecting the ZIP file and submitting.

I’m running WordPress 5.0.3. Here’s a list of my active plugins in case you’re aware of any conflicts (already tried disabling All-In-One WP Security):

All In One WP Security
Bluehost
Classic Editor
CMB2
Duplicate Post
Header Footer Code Manager
IP Geo Block
Kirki Toolkit
MailChimp for WordPress
Ninja Forms
Really Simple SSL
Responsive Filterable Portfolio
Stripe Payments
SVG Support
ThemeMountain Plugin
WP SEO Structured Data Schema
WPBakery Visual Composer
Yoast SEO

Thanks!

Is your zip file getting auto unzipped by any chance? You are 100% sure that you are selecting the addon’s zip file (not selecting another file by mistake)? If you fill in the contact form and provide access to the site, I will be able to take a look.
