Unhandled Promise Rejection Error in WP Admin

vickeryhill · June 2019

When trying to save a page or post in WP Admin that uses Muffin Builder I receive the following error in console.

Unhandled promise rejection

Response { type: "basic", url: "https://domainname.com/wp-admin/post.php?post=2379&action=edit&meta-box-loader=1&meta-box-loader-nonce=510e50bf8e&_locale=user", redirected: false, status: 500, ok: false, statusText: "Internal Server Error", headers: Headers, body: ReadableStream, bodyUsed: false }

wp-polyfill.min.js:2:31500

I'm able to save posts that do not use Muffin Builder. I don't have this issue when I switch to the twentynineteen theme.

Running WordPress 5.2.1 and Betheme 13.9.

Any suggestions?

Same problem.

Hello,

you BeTheme version is very outdated. You should update to the newest version. Also make sure your PHP version is 7.0 or greater.

Here is an instruction on how to update the theme: http://themes.muffingroup.com/betheme/documentation/#general Theme updates will not delete your content unless you have changed the files directly in which case we suggest using a child theme. We also recommend creating a backup file. Please remove the theme completely from your theme folder and install a fresh copy. Do not overwrite files. thanks

Upgrading solved the issue.

I purchased multiple BeTheme licenses at ThemeForest and can see 5 BeTheme
line items, but there's no way to tell me what license goes with what
site. What's the best way to determine what license goes with what site?

You can always check where your license keys are currently registered using this tool:
