Can’t edit thumnails – won’t load

For reference, I have already tried disabling all plugins, uninstalling and reinstalling NextGen plugin, etc…

Hi,

I am glad to help, is your server using any kind of CDN? If yes, please disable it and try again.

Please keep me posted.

Thanks.

Thanks for your quick response @jaimeimagely , no there is no CDN setup for the websites in question. Any other thoughts?

For reference, this is one of the sites having this issue, if you’d like to inspect more specifically: https://sallyanneupton.com/

Hi,

Could you please activate WP DEBUG and try again, send us the error in the error log afterwards, the devs might then have an idea of where the issue comes from.

Thanks.

I have enabled debug, restarted the server and run through trying to edit the thumbnails again, but the only “warning” showing is “NOTICE: /bitnami/wordpress/wp-content/plugins/better-wp-security/lib/icon-fonts/init.php:35 – Undefined variable: url
require_once(‘wp-admin/admin-header.php’), do_action(‘admin_enqueue_scripts’), WP_Hook->do_action, WP_Hook->apply_filters, it_icon_font_admin_enueue_scripts”

Hi @sarahsas,

Thanks. This notice doesn’t seem to have to do with the issue you are getting.

After accessing your gallery from Manage Galleries, you can press F12 key to open the browser’s DevTools then access the Network tab, select"Fetch/XHR" filter then press to edit any of your thumbs and access the request that’ll appear ( it should look like edit-thumbnail.php?id=100) and finally access the Response sub-tab to see what’s the request’s return.

Perhaps that’ll provide you with some ideas on what’s happening. Sometimes that’s because of the site’s or hosting’s firewall blocking the request and in that case – you’d need to whitelist it.

@imagely thanks for your guidance. When I check the response tab, it just says “This request has no response data available”. Under the Headers tab is the follow errors, as I initially mentioned:

@sarahsas,

Feel free to submit a report using the https://www.imagely.com/report-bug/ page and we’ll check it.

Thanks!

ok will do, thank you.

Hi @imagely, I have solved it.

The issue lies within this file: /wp-content/plugins/nextgen-gallery/products/photocrati_nextgen/modules/ngglegacy/ngg-config.php

The file path to wp-content needs to be updated because in Bitnami stacks, the structure is different. This is the fix:

/** Define the server path to the file wp-config here, if you placed WP-CONTENT outside the classic file structure */

$path = '/opt/bitnami/wordpress/'; // It should be end with a trailing slash

Once I added the “/opt/bitnami/wordpress/” bolded path, it all works. This bug/error will apply to anyone using a bitnami wordpress installation, most common for Amazon AWS Lightsail.
