JSON error on image uploading

@koolmind – We do not have any specific references to jquery.filtree.min.js in our code … have you tried deactivating all of your plugins, clearing your browser cache (and site caches if you are using a caching plugin), then reactivating the NextGEN plugin?

If this fixes the problem then it was likely one of the deactivated plugins that was causing an issue. Now, retrace your steps activating each plugin and re-checking to see if the problem returns. If it does then that last activated plugin was probably the one. Keep reactivating and in most cases it is also best to keep checking after each plugin, sometimes there may be more than one plugin on a site that will create an issue. If you do find one (or more) plugins causing this problem we would greatly appreciate your feedback on them so the developers may address them as soon as they can.

If the problem still persists after all of this we would still want to know, even more so, as we will still want to sort out the issue and may need additional details.

Thanks!

I believe there’s something wrong.
The complete path to the JS file is
<my_site_name>/wp-content/plugins/nextgen-gallery/products/photocrati_nextgen/modules/nextgen_addgallery_page/static/jquery.filetree/jquery.filetree.min.js

As you can see this JS file is part of your plugin.

I deactivated all other plugins, off course, but nothing has changed.

@koolmind – Ah, yes … you referenced filtree and as such it does not appear in our code but obviously jquery.filetree.js does.

It might be helpful to have a look at your site first-hand, can you share a link to where you have a NextGEN Gallery display inserted?

Thanks!

There’s no gallery on my site (not yet).
I receive all errors every time I try to upload a photo, in the admin panel.

If you want I can create an admin level account for you… but I believe that it won’t be usefull.

Try this:
[Moderator]Please do not share log in credentials on the forums.[/Moderator]

This user will be deleted into 48 hours.

These are my server config screens

I’m pretty sure that there’s nothing wrong… but feel free to check them out!

UPDATE
————
I’ve found the issue related to the javascript error. There’s a file (index.shtml) used to show a temprary site, while I’m building up the new one.
This file is wrongly parsed… that’s the error!

The real problem remains.
When I try to load an image several things happens:
1. database is updated, but gid fieldinto wp_ngg_gallery is always set to 0
2. no new folder inside gallery folder is created
3. no image is uploaded
4. the gray box that usually shows errors appears, but it’s empty.

No console error to report.
My error.lof reports this line:
[warn] [client 82.59.77.189] mod_fcgid: stderr: PHP Notice: Undefined index: import_singular in /var/www/vhosts/gpcomunicazione.com/httpdocs/wp-content/plugins/nextgen-gallery/products/photocrati_nextgen/modules/nextgen_addgallery_page/templates/import_media_library.php on line 16

All plugins are unactive and the twentysixteen theme is active

@koolmind – Try removing the index.shtml file or temporarily renaming it to something that your server will not use to load with (adding a ~ to the front of the file name will work).

Thanks!
