Can't create new modules!!!

I have tested again, but no luck. I have totally removed slideshow ck, then install it again and I can create any module
Are you using the 2.0.5 version of slideshow ck ?

if yes, then please send me an admin access by email so that I can check

I have fixed the problem in the "folder" plugin of slideshow ck, you can check on your website
This will be integrated into the next release
