I’ve managed to confirm this bug across at least two of my current Concrete sites. On the second site, I set up an extremely simple testbed to remove other possible factors. The testbed consists of a page called ‘list test’ containing an express list block and a page title block, and a second page called ‘detail test’ containing an express detail block, a page title block, and feature link block in the footer that points back to ‘list test’.
The express list block on ‘list test’ is configured to open ‘detail test’ and display the default form of the express entry selected from ‘list test’ – only it doesn’t. Nothing is returned, not even an error. If I look at the page source, all I see are empty divs.
I would like to know if anyone else has had this problem or could suggest a fix. The site I’m running the test on is fairly clean & simple: Concrete 9.4.3 / PHP 8.2.28, no Multisite, no advanced addons. This should work. Any insights anyone can share are very much appreciated.
