I can attach files only on new topics

[teokolo]

Hello,
attachments are not working as I expect anymore, I didn't have any problem in older versions.

If I create a new topic, I can add an attachment;
If I reply to a topic, I cannot add any attachment (I can find an error debugging XMLHttpRequest , initiator is plupload.full.min.js?assets_version=243 and error is:

Code: Select all

{
    "jsonrpc": "2.0",
    "id": "id",
    "error": {
        "code": -400,
        "message": "The submitted form was invalid. Try submitting again."
    }
}

I'm running phpBB 3.3.14 - php8.2 and I'm trying to upload a 50kb jpg as an administrator.

Is this a vanilla install or you did mods?

You can try to disable Javascript in the browser to possibly get real PHP error then on file upload attempt.
