A couple of days ago, my Libre installation stopped allowing access via the web interface. I get the following error when navigating to the interface:
“Composer detected issues in your platform: Your Composer dependencies require the following PHP extensions to be installed: curl, dom, gd, simplexml, xml.”
I have attempted to reinstall each of those extensions, but am told that it is already installed and at the most current version. It appears that Libre is still functioning just fine, as we are getting email alerts for our network devices. We simply can’t access the web interface to monitor things live. Any information you can give me would be much appreciated, as we very much need to monitor several problematic nodes at the moment.
