The process you describe matches what our documentation recommends
for removing container associations from descriptions. However, I just did a quick test in our public demo site and was able to remove a container association from a description there. Can you provide me with a bit more information, so we can offer further suggestions and/or determine if this is a bug in AtoM?
First, what exactly happens when you click the save button - do you get an error message, or does the page reload to the description, but without removing the container link?
Additionally, what is the full AtoM version number listed in Admin > Settings at the top of the page?
If I've found the right public-facing catalogue
for your institution, I noticed that you have a custom theme from Max Communications. Is your site also hosted by them? If yes, then I would recommend contacting them to investigate further. Most recommendations I have for you involve access to the back end of your application (i.e. the command-line), so either a local system administrator (if you are self-hosting) or someone from Max (if they are hosting) can use the suggestions below as a starting point.
in the edit page). We do have some recommendations for things to check in custom themes when upgrading in our documentation (here
), but it also depends on the theme itself and how it was developed, what it changes, etc. It could also be as simple as the theme CSS needing to be recompiled.
In general, when there are errors or unexpected behaviors, one of the first things we recommend is checking the webserver error logs to see if there's more specific information about the nature of the failure. See:
There's also Debug mode, which can sometimes catch errors that don't make it to the webserver, but is likely disabled by default on a production server:
If it's data-specific, then running some of the common maintenance tasks can often help to resolve issues. I recently shared a summary of these in another thread - even though it was for a different issue, these tasks can often resolve common issues. See:
Hopefully one of these suggestions will get you on the right track!
