lightbox slideshow not loading off of thumbnails

[maestroc]

Sorry, me again... I just finished updating several old J3 sites which use Phoca Gallery (5.0.3) to Joomla5. It also uses Phoca Gallery Slideshow Plugin (4.4.0). On the old site when a suer clicked on a thumbnail image like on this page:

https://bravo.sawstemp.net/binotesj3/george-vi

a new tab was opened with a slideshow control:

https://bravo.sawstemp.net/binotesj3/co ... t&Itemid=0

On the new J5 site this does not happen. Instead the user winds up being taken to a 404 error page. See the same example as above but on the new site (click an image to see the redirect):

https://www.indian-coins.com/britishind ... /george-vi

Instead we get this:

https://www.indian-coins.com/britishind ... t&Itemid=0

Do you have any idea what might be going wrong on the new site? Is there some setting that I need to adjust or some other plugin that I need to install? Worse thought, is the slideshow plugin not compatible with J5? I don't see it with a J5 icon on your download page.

I've been trying to troubleshoot this and figure out what is wrong. I went back to the old Joomla 3 backup and ran the upgrade again.
Everything works fine with the links on Joomla 3. The problem starts the second that I switch the site over to Joomla 4. Please see the video below for a visual walkthrough of the problem.

I also tried upgrading Phoca Gallery to the J4 version (4.5.5) and the problem is still there.

Hi, there was a change of router between Joomla 3 and Joomla 4 so there will be not the same links, see:

I am not 100% sure but maybe this is related to these changes (if I understood your problem properly)
