Users cannot I cannot delete entries from their vault when using the Chrome or Firefox addons. The delete option is simply missing from the hamburger menu next to each entry. It is also not to be found when editing the entry (think it used to be at the bottom?)
Not sure how long has been this way; I just noticed it today obviously it hasn’t always been broken. I can delete entries if i login to the server via the browser page. This is not limited to items in a collection/organization.
It seems, you are using an unofficial server software, which is not supported by Bitwarden, as it is an independent product. From time to time, there will be compatibility issues between the official Bitwarden client apps (browser extension, mobile app, desktop app…) and an unofficial server product, when Bitwarden implements changes to its own server software and/or client apps. “…Bitwarden cannot guarantee that official clients will work perfectly with non-official servers.”
(Also due to this - and for other reasons - we recommend using the official Bitwarden server software.)
It is generally not possible for members of the Bitwarden community (users or developers) to help with such issues - and with issues of the unofficial server itself. Please seek support in their community spaces.
If you can replicate your issue on an official Bitwarden server, feel free to open a new thread here.
