@Makoto Thanks. I tried it, and it does show the data-lists.css file. However, the Revert button appears disabled. I made it enabled via removing the ipsButton_disabled css class from it and clicked on it - however the operation fails with http 500 error.

Hi Makoto, thanks for your reply! Please let me know what trick you found that helps to resolve the issue. I am ok in general with core css files being locked, but I need to: 1. Compare the data-lists.css I currently have with the original version to determine modifications. 2. Revert data-lists.css to the original version. 3. Apply the modifications to custom.css. So I am currently stuck on the step 1.

When upgrading the forum I got a warning that the theme's file core → global → responsive → data-lists.css was modified/customized. This is ok as I modified many files and when upgrading I merge them. However, I can't find the data-lists.css file in the theme's editor. I can always find all files to merge, but not this one. The only css file I can see on the CSS tab of the editor is the custom.css file. Here is a screenshot:

Nathan, thanks! It was indeed the missing download permissions on that forum. Issue resolved.

A video attachment is automatically inserted into a post this way: <video class="ipsEmbeddedVideo" controls="" data-controller="core.global.core.embeddedvideo" data-fileid="42566"> <source src="https://domain/uploads/monthly_2022_09/filename.mov.586766f886744b354395822ed8ddf4d8.mov" type="video/quicktime"> <a class="ipsAttachLink" href="//domain/applications/core/interface/file/attachment.php?id=42566&amp;key=671c655c246018173227d863060e2069">filename.mov</a> </video> It works well when the video format is supported on a client - then it shows the embedded video. However, in case of a mov video file it's not supported on many Windows devices. In this case the embeded video is not displayed and there is an attachment link instead. However, when user clicks on that link it shows the error "This attachment is not available. It may have been removed or the person who shared it may not have permission to share it to this location." Note: the attachment was uploaded by admin, and the link does work if clicked from another admin account - it doesn't work only when clicked from a user (non-admin) account. The board version is v4.7.2.1.
