Adding Galleries – 'Save' doesn't function

I’ve been asked to fix a box that was hacked at some point and restored completely from a backup. WordPress was 2.7.1 and Nextgen was 1.2.something, or so I’m told. OLD!!! They upgraded WordPress to current and Nextgen to 2.0.66 before I arrived on the scene.

The basic problem now is that it seems impossible to add an album to a page, so that a thumbnail for each contained gallery is displayed. This evidently worked prior to the upgrades. Using [album id=3] (what they had when I started poking around) in the page text editor will show the thumbnails, but clicking one simply brings up the beginnings of the viewer and the spinning wheel… which goes nowhere. All the gallery thumbnails seem to have the same link associated (the page we’re already on), which doesn’t work as I noted.

Looking at: https://www.nextgen-gallery.com/adding-galleries/ I can see the process needed to add an album or gallery to the page. Trying this I get the window with:

– Select a display type
– What would you like to display?
– Customize the display settings
– Sort or exclude images
[save]

The first appears to be OK. The second behaves oddly and doesn’t alway seem to want to display what it should – the list of galleries doesn’t appear as the nextgen page suggests it should. The third appears to be OK. The fourth (sort or exclude) shows nothing in the dropdown. And most importantly, the ‘save’ button does absolutely nothing. So I looked for conflicting plug-ins.

The only other installed plug-in is ‘events calendar’ by Luke Howell… which is evidently also as old as the hills. Deactivating it seems to allow the save function to work, and the drop downs appear to function properly. However, the page editor (visual mode) inserts a red exclamation mark in a triangle where the album would reside.

Viewing the page produces the same result as manually inserting the [album] tag. Thumbnails appear, but the link they correspond to is the page already displayed. The screen darkens and the spinner spins, to no effect. The page editor (text mode) shows the insert function to have dropped this into the page (URL modified to protect the innocent)…:

<img class=”ngg_displayed_gallery mceItem” src=”https://www.website.com/index.php/nextgen-attach_to_post/preview/id–4137&#8243; alt=”” />

I can accept that the plugin calendar is part of the problem. They won’t want to switch to something else, but I can deal with that. However, disabling it doesn’t seem to completely solve the problem, so I don’t think it’s entirely to blame.

Suggestions as to what I should try next? Thanks!
