Thanks. The MSD issue looks fixable. There is a version on github that is ok in php 7. I’ll test it then include it in the add-on module so there will beni need for a Stuart’s download. It will work well with the Dropbox file back-up module I have just completed.
I’ll look at the shared note issue when I can.
I forgot to answer your other question. Yes, you can simply go back to php 5.6 with no issues.
