Slideshow Sometimes disappears

Most of the time, the slideshow works exactly as I expect it to, and is a fabulous addition to not only my front page, but sub-pages as well.

But every so often, it has happened twice in the last week, the slides just disappear from the page, though I have made no changes which could have caused this.
My usual solution is to open up the module using it in the module manager, save and close it, then it restarts again.
I am using joomla 3.4.1, so could this be the issue?
A fabulous tool - thanks so much for the work you have done on this.

Hi
unfortunately I can not reproduce the issue, the slideshow works great by my side
do you have a cache system enabled or something like this ?

Thank you for your quick response.
I am not surprised you cannot replicate the issue, as it appears random in nature and I have not been able to link it to any cause - I guess I will just have to keep my eye on it and continue to reset it when the slides disappear.
Thanks anyway.

I have found an error now

ReferenceError: Hash is not defined
www.kemble.co.uk/media/system/js/modal.js
Line 7

but I can not tell you from what this error comes ...

It appears that the error message you found (Hash is not defined, in the modal.js file) is a problem with Joomla 3.0, in that it fails to recognise "Mootools-More" but only "Mootools-Core".
As to how this relates to the slides showing or not, and how you found this error I am afraid is beyond me.
I also found reference to the Lightbox type "Squeezebox" when looking for information on this error message, but I have selected the type "Mediabox CK" on my site, given that I do not know the difference.
So the mystery remains.....

please go in the file
modules/mod_slideshowck/mod_slideshowck.php
at line 11 remove and see if it solves your issue
