Yes, I’ve been doing that every time I upgrade the files.
UPDATE:
I restored (files dated 7/25/2019) Blesta to 4.4.2 version (but not the db). Should I also restore the db to 4.4.2?
Note: Blesta was able to auto generate invoices on 8/1/2019 after I upgraded to 4.6. Sometimes after 8/1, I upgraded php, ioncube, and ngnix to the latest. And it’s probably the reason on 9/1/2019 invoices and services were not automatically renewed.
Also, I downgraded to php 7.1x, appropriate ioncube file version for php 7.1, and hot fix file for blesta. Now, all the links in the admin work without an issue.
Unfortunately, auto invoice and service renewals is not happening. I have run the cron job manually, and the run was successful.
What else should I try? I am thinking of moving the installation to an Apache web server.
Thank you.
