In phpFox Neutron, there's a feature as "Rebuild Core Theme" at AdminCP >> Maintenance. Its purpose is to compile all styles on all apps to one file to load. Hence this info is still vague and not announced commodiously, it takes to that some issues will happen as following. 1. Install/upgrade a new app >> its styles are not included in bootstrap file to load so the layout is broken 2. Upgrade a platform >> some styles perhaps are set as default so ones in apps are missing. Please always run two steps - Rebuild Core Theme at AdminCP >> Maintenance - Clear Cache at AdminCP >> Maintenance
