Cannot Read Property 'add' of Null Cannot Read Property 'add' of Null Slick

Hullo @staze

I have already shared with you some steps to bank check for existing conflicts.

Let me share that again:
1.- Temporarily deactivate all your plugins except NextGen Gallery.
2.- Is the problem solved? So, it was acquired by one of your plugins.
Delight check one past one and discover the 1 causing the problem.
3.- If the problem is not solved with the deactivation of the plugins, try changing to a standard WordPress theme, it could be a conflict with your current theme.

If y'all already did this, please let u.s. know.
We want to exist aware of whatsoever conflicts with our plugin.
Many cheers!

Completely dissimilar event. I just spun up a completely new test site, completely new install of NGG. Added 2 slideshow widgets to the folio, and got this fault.

Over again, it seems to be because it'due south trying to add "slick" a second time, just since it's already there, it errors.

            Uncaught TypeError: Cannot read holding 'add' of nil     at east.initADA (slick.min.js:1)     at east.init (slick.min.js:i)     at new e (slick.min.js:i)     at a.fn.init.i.fn.slick (slick.min.js:2)     at Object.<anonymous> (ngg_basic_slideshow.min.js:1)     at Function.each (jquery.js:two)     at HTMLDocument.<bearding> (ngg_basic_slideshow.min.js:1)     at i (jquery.js:2)     at Object.fireWith [as resolveWith] (jquery.js:2)     at Function.ready (jquery.js:2)     at HTMLDocument.Thousand (jquery.js:ii)          

Run into link I posted to start with. Somehow NGG needs to be inverse to address this. I'm an NGG Pro owner, should I submit this as a ticket at that place?

Just updated to iii.ane.5 of NGG, and this effect even so occurs.

How-do-you-do @staze

Nosotros already have ticket number #262264 related to this forum thread.
We'll go on the conversation from at that place.

Howdy @gabyimagely,

I'm non seeing ane as waiting for customer. Both say "In Process".

Could you mean the other ticket that's been filed nether this bug?

Howdy @staze

Apologies. You have 2 bug reports and ii forum threads.
I was writing near this other bug report: "NextGEN Pro – slick.min.js error" #272014.

In our terminal communication, yous mentioned this "I will update WordPress and I will meet if it is fixed. I'll tell you…"

So, that'southward why it's currently waiting for some feedback.

Feel free to write u.s.a. back!

Pitiful, I don't see that bug on your site… I see 266063 and 262264.

Both of those are waiting on developers I believe….

Howdy @staze

Apologies
The consequence is was that we had two tickets on the same forum thread.
But the other one is from some other user @marknopfler.

Once again, We are sorry.

– Gaby, Client Support.

Was in that location ever a solution for this slick.js error ? Please share.

Got it working (on free version). If yous're using the basic slideshow gallery, open the file /wp-content/plugins/nextgen-gallery/products/photocrati_nextgen/modules/nextgen_basic_gallery/static/slideshow/ngg_basic_slideshow.min.js

and change information technology to this https://pastebin.com/3ytzp9WM

You're merely fixing the slick js being initialized every fourth dimension there's a gallery on a folio – .not('.slick-initialized').slick({})

Yous'll have to flush the enshroud to see the changes to this file equally it's versioned in the queue. Or you could dequeue that js file and create your own so that you're not editing the core plugin files.

Hope that helps.
