ah sorry we cross posted
I ask members to backup on most threads just to be sure people have backups - as I get older I am more paranoid about random breaks of sites
With the zentools version you have installed if you update the php version at some future date you will encounter problems
So updating zentools is something you will have to do at some point
but with the sql error it isn't something I've really ever seen with this module so hoping an update might also help
Thanks
