Slick error, may be related to multiple widgets

Hi @staze

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

Let me share that again:
1.- Temporarily deactivate all your plugins except NextGen Gallery.
2.- Is the problem solved? Then, it was caused by one of your plugins.
Please check one by one and find the one 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 you already did this, please let us know.
We want to be aware of any conflicts with our plugin.
Many thanks!

Completely different issue. I just spun up a completely new test site, completely new install of NGG. Added two slideshow widgets to the page, and got this error.

Again, it seems to be because it’s trying to add “slick” a second time, but since it’s already there, it errors.

See link I posted to start with. Somehow NGG needs to be changed to address this. I’m an NGG Pro owner, should I submit this as a ticket there?

Just updated to 3.1.5 of NGG, and this issue still occurs.

Hi @staze

Unfortunately, www.remarpro.com doesn’t allow us to address pro support questions here in the free forum. We can only address NextGEN Gallery [Free] questions only.

We already have ticket number #262264 related to this forum thread.
We’ll keep the conversation from there.

Hi, same error here using pro version. I updated ngg and ngg pro but issue is still there…

Hi @gabyimagely,

I’m not seeing one as waiting for customer. Both say “In Process”.

Could you mean the other ticket that’s been filed under this bug?

Hi @staze

Apologies. You have two bug reports and two forum threads.
I was writing about this other bug report: “NextGEN Pro – slick.min.js error” #272014.

In our last communication, you mentioned this “I will update WordPress and I will see if it is fixed. I’ll tell you…”

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

Feel free to write us back!

– Gaby, Customer Support.

Sorry, I don’t see that bug on your site… I see 266063 and 262264.

Both of those are waiting on developers I believe….

Hello @staze

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

Again, We are sorry.

– Gaby, Customer Support.

Was there ever a solution for this slick.js error ? Please share.

Not that I’m aware of.

Got it working (on free version). If you’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 it to this https://pastebin.com/3ytzp9WM

You’re simply fixing the slick js being initialized every time there’s a gallery on a page – .not(‘.slick-initialized’).slick({})

You’ll have to flush the cache to see the changes to this file as 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.
