Nothing happens when clicking on Add Input

We have discovered another issue within Omeka that we did not know about previously. This morning, Elizabeth was attempting to create Dublin Core records, and one of our buttons is not working. When Elizabeth creates a record, she clicks on “Add Input” to allow her to add subject terms. Clicking on this button usually creates a second text box for her to do this, but now we do not have that ability. None of the add input buttons show another box, not just subject. Here are some screenshots to better explain the problem that we are having:

What user permissions does Elizabeth have? What version of Omeka Classic are you running, and what plugins do you have installed and active?

The Elizabeth account has super user access.
Add Item Link, Bulk Metadata editor, Clean url, collection tree, CSV Import, Docs Viewer, Dublin Core Extended, Exhibit Builder, Facet by Metadata, Hide Elements, History Log, Item Order, Item Relations, LC Suggest, PDF Embed, PDF Text, Reports, Search by Metadata, Simple Pages, Simple Vocab, Subject Browse, Videostream

Can you check to see if you have any errors in the browser’s Javascript console? Often the shortcut to open it is Ctrl + Shift + J.

I am not sure if this is correct

That looks right, but doesn’t really show any errors.

I should clarify some more, too: we’re looking for this console output from the user having the issue, on the problematic page, after clicking the Add Input button. Is that what you posted?

This is what a co-worker is getting.

I also am getting nothing when I hit add input and I showed the browser console.
The top image is from the Firefox browser on the server and it registers nothing as far as JavaScript goes.
I sent an email to the person who told about the add input not working and that is the second screen shot. It looks like the error is not registering in the browser.

When you say you “get nothing” when you click Add Input, does that mean the button doesn’t work, or just that it causes no extra output in the console? In other words, is it just one user having this problem, or is it everyone?

The other user’s screenshot looks like it’s from Microsoft Edge: is there any difference from other browsers, like Chrome or Firefox? I’m also noting that the console screenshot references “login” as the page the errors are occurring on: is this the console output of the add/edit item page, or somewhere else?

The problem is happening for everyone. When we click on add input the browser starts like it is doing something but nothing comes on the screen.
I have tried different browsers and it is the same. I have booth chrome and edge on my computer and they both act the same.
I also have a Firefox on the actual server and when I click on the add input button, nothing comes on the screen.

Hmm, it’s difficult to really pin down “remotely” with no error messaging…

This is something that used to work but now doesn’t, right? A worthwhile test would be to temporarily disable all your Omeka plugins (or ones that you know were installed more recently) and see if the problem persists.

You can also try to enable error display and see if any errors are reported on the page itself. There may be an error, for example, at the very bottom of the page, preventing it from being rendered in its entirety.

I turned on error messages by taking away the comment and here is what I get now. I added Test TCC 50 to the lines and his add input and this is what I get.

And what happens if you go to http://libraryservices.tulsacc.edu/omeka/admin/lc-suggest/index/suggest-endpoint-proxy/element-id/50?term=Test ? Those look like unrelated errors from the LC Suggest plugin, but it’s possible a useful message would be displayed there.

So, there are no errors elsewhere on the add item page, like at the bottom? Looking for that was the basic purpose in turning that error display on. Basically, if you scroll all the way to the bottom of the Add Item page, do you see this:

or do you see something else?

Omeka has encountered an error

OK, I think that’s just unrelated.

What about the second half of my question, about the bottom/footer of the “Add” page?

I do not see any errors on the top or bottom of the page

I turned on logging and this is the file that was generated:

At this point, I think your best bet would be deactivating all your plugins and seeing if that resolves the issue. If it does, then you know that it’s a plugin that’s the culprit, and can reactivate them one-by-one and narrow it down.
