Impossible to comment

Hello Matt,

this is the full output. Nevertheless I send you a screenshot. I'm using neither git nor SFTP. With my shared hosting everything is allright, no problems there. As I said before it's the AT theme. When I switch to any other theme commenting is no problem.

Regards, Reiner

Hello,
I just wander what the state of this issue is. It is still impossible to comment on nodes. Whatever I try, it doesn't work. I sent you what you requestet one month ago. And now?

I haven't done anything with the comment field, but I had changed the form layout. I've hidden the comment title field. No Problems with other themes. Now I put the title field back again, flushed chaches, ran cron - same result. Impossible to comment.

I just added a new comment type where all settings are exaktly the same as in the default comments. (Except the system name of the comment type, of course.) And that works! :-o I added a comment field of the new type to a node type, now I can comment on nodes of this type.
That is good news on the one hand, on the other hand I ask myself what to do with all the existing comments and why commenting doesn't work with the default comments.

@sd123: No. I did switch from D7 to D9 but I didn't umgrade. I made everything new in D9 and managed the migration myself. And once again: the problem occurs only with AT. No Problems with other themes.

@all: Now I deleted the comments field from the content type I used for testing and added a comments field of default type. Then again commenting doesn't work. I tried both options, adding the existig field and adding a new field. Same result, same error.

As I said months ago there are no more entries in the error log than the one that is shown in the screenshot. The important thing ist the "null" at the end instead of a URL. Well, there is one more entry, it is "access denied" because the access to the URL created by AT theme is denied.

In order to recreate the malfunktion you need a website that was built with any other theme than AT and that has comments. Then install AT, switch to AT and post a comment. Then you'll have the error.

Meanwhile I have installed a couple of further themes. AT is defenitely the onle one that produces this arror.

@rossidrup: I don't have the problem with editing nodes. My only problem is the commenting.

I wrote that already on Feb. 9th. I created a new comment type and added a comment field of the new type to a node type. That worked. But that's good for nothing because I have plenty of existing comments. They are important.
Why should the existing comment field not exist in AT? And if, then why are existing comments shown in AT? If the "old" comment field is shown, it must exist.
But your post/question leads me to another phenomenon. Since things worked with the new comment type I had the idea to simply convert all comments of the type "default" to the new type. Let's call the new type "test". At first I did that manually in the database for a few comments. There are three affected tables: "comment", "comment_field_data" and "comment_comment_body". I changed the feld "comment_type" from "default" to "test" in those three tables. But on my website I stll saw the default comments. I deleted the default comments field from the content type and added a test comments field. Then I didn't see any comment. And, of course, commenting an the default comments field didn't work.
Then i took the module Convert Bundles and convertet the default comments with that. Same result. The same field in the same tables was changed, my website still showed the default comments and didn't show the test comments.
That means: there must be another table in the database which stores information on comment types. A table that also the module Convert Bundles doesn't know. Do you know which table that could be???
(By the way, this module workes fiine for node types.)

@rossidrup
I tried at least four themes. AT is the only one with that problem. I said that several times before. Maybe you didn't read my posts on this issue.
