I’m going to attempt an upgrade of the web server to Ubuntu 19.10 tonight.  This will include an upgrade to PHP 7.3, however, this is likely to break a few things initially.  If web mail is not working late tonight, be patient.  Typically PHP makes syntactical changes that requires the upgrading of some applications but it is impossible to know which in advance.

     So what I am going to do is take it down for about half an hour this evening to make a current backup in case I can not get all the applications to work with 7.3 and we need to back out.  Like most PHP upgrades, newer versions are faster and therefore preferable if we can get all the applications to work.
