I’ve been using this plugin for >12 years without any problem. It’s running now on WordPress 5.6 and PHP 7.4 on >20 sites I maintain. I have none of the problems described in threads like this one. If I was any good at coding PHP I would take over this greatest of all image plugins. For me this plugin is still alive and kicking. I hope somebody will make it shine again for the rest of the world and keep it reliable for the future!
note: it always was a free plugin: this is the original nextgen legacy

It’s the update of WordPress SEO that’s causing the problems here
Turning it of the error messages disappear

I just updated this site. On another similar site the update went OK. Looking into it now

I get the same error messages after this updat

In “Edit Slideshow” there is no division in the layout between the different slides anymore.
It mentions the slides like this:

Slide 1 Drag Toggle Delete

And the Drag Toggle Delete doesn’t work

I updated through the admin and also uploaded manually through ftp but no difference

I solved the problem. In this setup I had changed the wordpress folder name into ‘gallery’. Evidently this confused the nextgen script and it sent these safemode error messages. I changed the wordpress folder to ‘galleries’, made a new setup and now my beloved nextgen is working flawlessly. Good!
