Hi,
Sorry for the late response, I haven’t had much time since last week.
Thanks to you and Steven, the problem has been fixed and I thank you for your help.
I am explaining to you what happened because in reality, there was a problem which led to others and it was not easy to resolve everything quickly.
First, the server’s version of Postgres was no longer compatible with the latest versions of the forum. I was using version 10.
We had to discover this problem and fix it. And to fix it, you had to update Postgres but the server didn’t have enough disk space for that. You need at least double the capacity of the forum because it duplicates everything. So I had to increase the disk space of the forum. Once this was all set up, the Postgres update went smoothly and so did the forum update. There were some cold sweats, especially on the reliability of the backups, but everything went well afterwards.
Here is the process to do:
1 - Edit the app.yml file and change the postgres10.template.yml line to postgres.template.yml
2 - Save changes
3 - Increase server disk space
4 - Update Postgres
5 - Update the forum
I hope this can help other people who have been in my situation.
See you soon
