I've attached a patch, you'll need to unzip it and replace the enclosed js/xf/attachment_manager-compiled.js file, which should resolve this. You'll want to rebuild the master data and/or clear your browser cache to pick up the changes, too.
Search for "How to extract a ZIP and upload the extracted files to a webserver" using your favorite search engineering or AI assistant.
It's not really rocket science.
has anyone had an issue with Google Analytics GA4 since they applied this patch ? mine has stopped capturing data at the exact time the patch was applied... very odd
