Remove IDs from URLs leads to problem with Slideshow CK and Joomla

Hello

I'm using Joomla (3.9.12) and Slideshow CK (2.0.9; Free).
If I'm removing the ID's from my articles the sites/articles which contain a Slideshow are no longer working.
After disabling the Slideshow everything works perfekt.
Is there a bug in Slideshow CK or I'am doing something wrong?

Kind regards
Mathias

Hi
can you please give me more infos :

sites/articles which contain a Slideshow are no longer working

what is not working ? please detail the problem

please give me the url of a page where you get the problem

Is there a bug in Slideshow CK or I'am doing something wrong?

we have to work on that together to find the problem, by my side I have no info about this problem, you are the only one to get it

Let me know
CEd

Thanks for the fast reply.

On my local test page i receive this error message instead of the article:

Fatal error: Cannot declare class ContentRouter, because the name is already in use in C:\xampp\htdocs\roadbear\components\com_content\router.php on line 214

This is the url of the page: www.roadbear.ch

I will give you backend access via mail.

ok. can you please make a test
- unpublish the slideshow (problem removed), then publish another module (mod_login for example) in the same way and article
>> tell me if you get the same problem or not
- tell me how you are loading the slides : slides manager, article, folder ....

if I puplish the mod_login exact the same way as the slideshow I get no error. The site works.
What do you mean with "how are you loading the slides"?

For every slideshow I have a module which is puplished in the selected menu or article.

ok great, another simple test :
- use a new Slideshow CK module with the demo data, just create it and save without changing anything (except the position, state, etc)
let me know if you have the same issue there
