admin/pages/edit/show/ID throws 404 errors

Silverstripe Version:
4.9

Question:
Hi There,

I have an odd issue (odd for me, I guess there’s a rational answer somewhere)

So my back end works fine for all DataObjects, I can also have the list of Pages and on the local version I can access the editing of the Pages through admin/pages/edit/show/ID_of_a_page

Though for some reason, after everything worked properly on the VPS for weeks, I have an error 404 only for the editing of pages, all the rest works fine. I have many mixed content error, but I guess it comes as the result of the root cause, as the rest of the site doesn’t throw any mixed content error.

So after spending my entire day on it without understanding where the issue could come from, I would like to ask if anyone would have a clue of what is happening?

Details of your query go here

I have these lines first in the Console

​ Function block inside entwine definition does not take $ argument properly
warn @ /_resources/vendor/s…r.js?m=1679783719:1
​ console.trace
warn @ /_resources/vendor/s…r.js?m=1679783719:1
8:1 Failed to load resource: the server responded with a status of 500 (Internal Server Error)
8:1 Failed to load resource: the server responded with a status of 500 (Internal Server Error)

then I have a list of different mixed content errors which don’t appear on any other page, so not sure that it’s the root cause. In any cases, I haven’t find any way to solve this issue.

Often this message comes with a more detailed error message in the network tab of the developer panel. Alternatively, you can check your logs to see if there are any more details about the error there.
