After update, FreePBX GUI shows 'Whaa' on top of the page and System Status report page stops loading

Hi,
I just updated 2 modules (cidlookup and systemadmin) and now all of a sudden the main page [myserver]/admin/config.php shows ‘Whaa’ text at the top of the page. (as do ALL the FreePBX GUI pages too) I can log on and log off, it makes no difference - the System Status page does not finish loading any more…

(btw the update process did not finish properly, there was a timeout message some time after pressing ‘Apply Config’ - but alas it seems I can access other settings/modules and phones are still working)

FreePBX 12.0.62
PBX Firmware:5.211.65-12
PBX Service Pack:1.0.0.0
