I can confirm this for Version 6.5.1+240320 (self hosted). We first saw this in 6.4.0, but after updating to the latest version the issue is still present. Please see screenshots attached for chrome and firefox

Have been testing in different ways, in different versions, in different browsers, with and without cache, and I couldn't reproduce it.

I can not reproduce this issue any more as well. Tested with 6.5.1 and 6.5.2 in multiple browsers. @schwadtke@demogr.mpg.de can you still reproduce the issue? I need more info about the error or I will close this since the issue is not reproducible.

I can still reproduce the issue. What info do you need?

For example if you can see any failed requests or errors in the developer tools in chrome.

How to get to developer tools:

1. Click on 3 dots in the right upper corner of the browsers toolbar
2. Click on "More tools" and then on "Developer tools"

If you look at the screenshot, the console is below and shows an error on this page and failed requests are above marked with red icon with a black cross inside.

I assume that something with the KCFinder is not loading properly.

For example this request that is successfully finished in my local instance (2nd screenshot http://ls-ce/vendor/kcfinder/browse.php?opener=custom&type=files&CKEditor=email_invitation_en&langCode=en)

Please find two capture videos attached. In Chrome, when clicking "Add file" the browser crashes, in Firefox on the first click it works, the following tries give that blank window. Chrome version is 123.0.6312.86 (Official Build) (64-bit), Firefox version 124.0.2 (64-bit).

Thank you. This is what I get when I click "Add file" in Chrome. No error, but browser crashes.

@gabrieljenik does this information help you?

I was able to reproduce it but not anymore. So I think this was a bug in Chrome.
So, whoever can still reproduce it. Can you let us know version of Chrome you are running and then maybe try to update and see if you can still reproduce?

I can still reproduce the issue as described above in Chrome (123.0.6312.106) and Firefox (124.0.2). Are we the only one who have that issue?

I can reproduce the issue (Windows, Firefox). But only if there are multiple upload questions in a group and only for the second and following questions (see bug report 19388). If there is only a single upload question, I cannot reproduce.

I managed to reproduce it on Chrome Version 124.0.6367.62. App version 6.5.4+240422.
When I click on Add file in the Email invitation template, I get grey overlay and can't do anything, even refresh doesn't work.
After some time, I get "Page Unresponsive".

@gabrieljenik Can you give it another try, please?

I will

@p_teichmann resolved this today.
