#1 have you cleared your cache
#2 are you using a custom theme

I fixed it by upgrading through my host provider. Something may have got messed up--not sure.

But, for future reference, I did clear the cache, etc. And, it was happening even with Plain Yogurt, etc.

Thanks!

I am having this same problem, any idea what you did fixed it. I recently upgraded to 5.4.1 and thats when the problem started.

Me, three! I'm running 5.4.1.1 and haven't experienced this issue with the slideshow before — I've installed loads of concrete sites. I've poked around a bit, but see nothing suspicious that might explain it. Can't say I've experienced this with other sites running the same version, but then I'm not sure off of the top of my head if my other sites of the same version are using the slideshow... maybe that's why I didn't notice it? Guess I'll continue poking and try to find a pattern...

I had the same problem but when i cleared my cache it worked just fine.

Yeah. I think this was a cache problem. Somewhere between my versions, the default css for the slideshow was moved out of view.php and into a separate file (view.css) in the slideshow block directory. My dev server is truculent, so once it thought the view.css file didn't exist it wasn't enough to clear my cache, I had to actually unmount and remount the file server that hosts my web files from my webserver.

Be wary of blocks that now depend on external css that didn't used to!

I probably caused the problem for myself. I made a custom block template (purpose: removing those annoying image links in set-based slideshows) but didn't make a copy of the externalized slideshow css that absolutely positions the images on top of each other. My dev server was then convinced that it couldn't be found anywhere, even after I deleted my custom template while troubleshooting. Harrumph.

Just an addendum... I recently used the automatic dashboard upgrade function to upgrade a site from 5.4.0 to 5.4.1.1. The view.css file for the slideshow block was not included in the automatic upgrade and I witnessed, again, the curious slideshow stacking problem. I had to grab a copy of the full install and poach the slideshow block view.css in order to fix it. I hope that was the only file that was missing!!!

What I found was when I duplicated the slideshow folder to teh top level blocks I only uploaded the view.css and had this problem. When uploading all the files in teh folder it was fine.

I'm having the same issue trying to use a use a slideshow from the Global Scrapbook. I've cleared the cache etc...
If I use the slide show function normally (add it to a page as a block) it works just fine, but if I add it via scrapbook then I get the stacking problem... Any ideas?

Update:
After some poking around I've identified part of the problem. When the block is being called from the Global Scrapbook the view.css is lost which is why the images are stacking on each other. However I haven't found a solution :(

You could just take the contents of the view.css and put it in your main site css. That would probably work.

I had the same problem.

Big thanks to dojodesign! That quick fix solved the problem.
