Broken WebUI only showing Overview, Devices and Ports but nothing works

My LibreNMS is running on an Ubuntu 16.04 and since some days the WebUI is not working anymore. The page opens and shows Overview, Devices and Ports but no Dashboard and non of the links is working.

I can’t find any usefull logs.

====================================

Component Version
LibreNMS 1.39-100-g02348be
DB Schema 251
PHP 7.0.30-0ubuntu0.16.04.1
MySQL 10.0.34-MariaDB-0ubuntu0.16.04.1
RRDTool 1.5.5
SNMP NET-SNMP 5.7.3

====================================

[OK] Composer Version: 1.6.5
[OK] Dependencies up-to-date.
[OK] Database connection successful
[OK] Database schema correct

I tried the actual version of chrome, firefox and safari to access the page.

What Auth method are you using?

I am using the standard integrated auth.

What else have you done in troubleshooting?

Not that much. Did try to manualy update what worked. Checked some Logs but I am not sure which one could be the one to check for such a failure. It looks like Librenms is working correctly (Poller and Alerts) only the GUI is broken.

I have changed the $config[‘php_memory_limit’] = 128; value in config.php to 1024. Now the WebGUI is working again.
