However, recently I installed a new plugin, and after running composer install, a list of plugins updated (which I do not have a snapshot of.) the placeholder is not working as expected.
What could have affected this, what is a potential area where I could start my investigate from to diagnose this problem?
If I were in your situation, I would start by comparing the current state with the previous one to identify any changes. If you don’t have a backup to reference, try checking the browser console for any errors or issues with loading file assets. That might give you some clues.
Can anyone please help, I have tried but nothing has helped thus far. and I had utilized put scripts a lot, and if this doesn’t get sorted, I will have to restructure the whole thing
We have browser tests that check that this feature is working all the time, so it must be something to do with your configuration. Interesting that it stopped working after an upgrade.
Try making a fresh installation and see if you can reproduce the problem in isolation. If you find that it is working there, continue to introduce variables (structure, plugins, etc.) from the site that isn’t working. Following this process you should find which element causes the issue.
If it occurs during a fresh installation, it could be a bug, provide us with the replication steps and we can take a look.
