Placeholder issue for jQuery 4.0.0 compatibility / issues.

Thanks @petecooper. It looks like we are hold by jQuery file uploader that uses few removed methods.

My local txp runs jQuery 4 beta, so far so good. Should we try using it in dev, to enlarge the testers pool? We'd switch back to jQuery 3 of course if txp 4.9 is released before jQuery 4.

Demo server is blocking something, not sure what.

[petecooper]

I can have a look - what can you see?

[bloatware]

Not able to save an article, for example. This shouldn't be directly related to jQuery 4 since it works on my localhost.

[petecooper]

Refused to execute https://dev-demo.textpattern.co/dev/textpattern/index.php?_=1716559654637 as script because "X-Content-Type-Options: nosniff" was given and its Content-Type is not a script MIME type.

Might that be it?

Edit: console output when saving a (new) article.

[bloatware]

Yep, it looks like a csp conflict. Ironically, jQuery 4 intends to solve them.

[petecooper]

I'll see how I can workaround it in the meantime, leave it with me for now.

[petecooper]

I'm a little perplexed - this appears to be solved, yet I haven't changed anything. Are you able to reproduce, @bloatware?

[bloatware]

@petecooper oops, sorry, I thought you have seen. We'd rather do some tests locally before pushing it online.

[petecooper]

Now seen 👍

I can of course reproduce the issue when the X-Content-Type-Options "nosniff" header is present. Once that is disabled (header unset … in textpattern/.htaccess), I still have saving issues on the Write tab (actually, no way to Save anything, old or new article) – both my old test site and a newish fairly default installation.

The Firefox console reports:

As a warning
The script from “http://txpdev.local/textpattern/index.php?_=1716781530549” was loaded even though its MIME type (“text/html”) is not a valid JavaScript MIME type.

As an error:
Uncaught SyntaxError: expected expression, got '<' (index.php 1:1)

I suspect there is some attempt at setting a response header that fails

–^–

All other panels behave correctly as far as I can see, images/files are uploaded or replaced, categories created, preferences saved. The few admin-side plugins active do what they are supposed to… etc. This testing with a fairly strict set of CSP directives (in config.php)
