The issue you are facing:
Upgrade from 13.0.7 to 14.0.4 failed.
Web page says that apps needs to be upgraded but the “start upgrade” button does not launch anything.
Since this is a shared hosting, i have no command line access.
How can i move forward? Help please!
Is this the first time you’ve seen this error? (Y/N): Y
Steps to replicate it:
- upgrade from 13.0.7 to 14.0.4 on shared OVH hosting
