Gallery Settings Not Saving After Update

Same here, not sure if this is new due to WordPress 5.5.

Same problem here. Whenever I try to make any changes to the Settings and try to save, it displays the following error –

Error thrown
Call to a member function save() on null

Even if I try to import existing images to the Gallery it displays the same error. I guess the error is related to an upgrade to WordPress 5.5

I am getting the same today. I haven’t tried to make any changes to Gallery Settings for a few months, so I am not sure if it relates to any recent updates of the plug in or WordPress?.

When I try to Save Options, I get:
“TypeError thrown
Argument 1 passed to iterator_to_array() must implement interface Traversable, null give”

I have emptied my Chrome cache and re-booted y desktop but no change.

Any ideas?
Cheers, Irene

Sorry I forgot to mention, my above problem is displayed on this page:
wp-admin/admin.php?page=ngg_other_options

Yes, I am having more problems with the NextGen Pro plugin. It seems that trying to open any of my pre-existing galleries on the page below give me the same TypeError message as well:
wp-admin/admin.php?page=nggallery-manage-gallery

It seems that I can create a new Gallery but I cannot access any of my recently created ones prior to today. Aaargh! ;-(

Hi everyone,

We are sorry to hear of the encountered issue. We are still inspecting to see why this issue happens for some of the installations only since we weren’t able to replicate it on our testing instances but we had a couple of reports for it until now and those should be enough for our developers to get an idea of a possible fix.

We’ll keep you updated in case of any findings on this one.

In case that you want to roll back to the previous version of NextGen Gallery, you can download it from https://downloads.www.ads-software.com/plugin/nextgen-gallery.3.3.6.zip then go to your site’s “Dashboard -> Plugins”, deactivate and delete the current version of NextGgen Gallery ( this is a safe procedure and you will not lose any galleries or settings ) then install and activate nextgen-gallery.3.3.6.zip

Bit of extra feedback. I had to take my main site back to WP5.4.2 due to all the 5.5 bugs, mostly from NextGen. However the originally reported issue above still occurs (as somebody else said, it’s not often we need to save a new setting so this may have been introduced further back). I’ll give NGG 3.3.6 a try and let you know if it goes away.

Right I put 3.3.6 on under my WP5.5 install and the settings saved without problems, but then I upgraded to 3.3.10 and the aforementioned error returned when trying to save. So it’s definitely been introduced with the 3.3.10 update.

Hi everyone,

We have issued a new update for NextGen Gallery that fixes most of the previously reported problems. Kindly update to the latest version and let us know if that fixes the issue.

Still getting the same error.

Hi @ispreview,

Thank you very much for your feedback. Just to make sure that we have understood it correctly. Are you referring about the settings not being saved problem or a different issue ( since NGG 3.3.10 introduced a couple of them )

Try to see here: https://www.hydraitalia.com/galleria/
If you try to click one of the thumbnails, you can see that the image opens but it is no longer possible to close it or browse …

Hi @stilweb,

Looks like your case may be different since the theme itself throws a couple of JS errors. To note here that in WP 5.5 they have bumped the jQuery version which caused conflicts with other products as well so you will have to temporarily switch to a theme from the Twenty series to see if this solves the problem.

If it solves the problem – you will have to reach the theme provider support to ask them for help getting the theme ready for WP 5.5.
