Problems with Enable/Disable

Hi all.

I have finally migrated across to our new CentOS 7 with Xymon 4.3.27-1.el7.terabithia and now have problems using Enable/Disable from the web interface. When I disable a test, the page returns as per usual but nothing is disabled.
If I run the:

xymon xymonserver.fqdn 'disable hostname.test 16871392s Disabled by: reason' 
command from the shell then it works fine.

I can load the /xymon-seccgi/enadis.sh URL without errors and it shows the currently disable tests/hosts.

There are no errors or messages relating to enadis in the apache or xymon log files.

Short of installing a debug build of xymon is there some way I can further debug this issue?

Thanks,
JT
