What version did you upgrade from - This is a Joomla 4 error message, did you know you were upgrading to Joomla 4? Did you take all the precautions, advice, migration planning, backups and tested backups before upgrading your site to Joomla 4?

I was upgrading from Joomla 3.9 to 4.0.1.

I backed everything up through Akeeba backup per instructions. I am really a beginner beginner and have no idea what to do.

3.9 is a whole series, not a version. There are 28 versions in 3.9.x and then there is 3.10.0 and 3.10.1...

If you did not upgrade to Joomla 3.10.1 and resolve all your compatibility issues then you just destroyed your site but not reading the very clear instructions on joomla.org

You will need to restore from your last know good backup.

You should close this issue here, this GitHub Issues tracker is for reporting bugs, not for seeking support. Sorry.

I was upgrading from Joomla 3.9 to 4.0.1.

Did you do that in one step, not with 3.10 in between? If so, then you should know that is not supported. Updates to 4.x have to be done from 3.10.x. This is written in EVERY release announcement for 3.10.x and 4.0.x releases, and it is also described here: https://docs.joomla.org/Joomla_3.x_to_4.x_Step_by_Step_Migration - mind the big red box at the top!

You know, I'm panicked right now after losing this website. I did read. I can't remember the version off the top of my panicked head, but after checking, reading, reading more, I thought I was doing the correct thing. This forum is fantastic for people chastising you and not so great for help.

Thanks.

I’m sorry you feel “chastised” but this is NOT A SUPPORT FORUM.

@angecityrock https://forum.joomla.org/ is a better place to asked question like this, this here is for bugs within the software.

You stated you have an Akeeba Backup - well read this:

https://www.akeeba.com/news/1748-joomla-3-10-and-4-0-common-issues.html

Especially the sections entitled:

• I upgraded to Joomla 4.0 by accident and my site is broken
• I cannot restore a Joomla 3 backup on top of Joomla 4; the site is broken.

Then before upgrading to Joomla 4.0.x again read these:

• https://docs.joomla.org/Planning_for_Mini-Migration_-_Joomla_3.10.x_to_4.x
• https://www.joomla.org/announcements/release-news/5845-joomla-4-0-and-joomla-3-10-are-here.html

How can I upgrade my site to Joomla 4?

Don’t stress, you’re not alone, we are guiding you for the mini-migration.

The first step will be to update your site to Joomla 3.10. We invite you to read Joomla 3.10 The Pre-update Checker https://magazine.joomla.org/all-issues/may-2020/joomla-3-10-and-the-update-checker. The 3.10 update checker will tell you which extensions are compatible with Joomla 4.0 (great, isn’t it?).

And then, you just have to follow our step by step tutorials. You can find them on our official documentation at https://docs.joomla.org/Why_Migrate. Planning is the most important part of the mini-migration process. See https://docs.joomla.org/Planning_for_Mini-Migration_-_Joomla_3.10.x_to_4.x to start with. At the bottom of that doc, you can then proceed to the step by step for mini-migration from 3.10 to 4.x. and specifically start with planning at (you’ll find plenty of information and tutorial about Joomla 4 on JDocs).

Note: we advise you to first test the migration on a copy of your production site.

You may also wonder if you have to migrate ASAP? You can take your time, we’ll support 3.10 for 2 more years. So your site is not at risk if you don’t upgrade now. And don’t forget that some of your extensions may not be yet ready for Joomla 4 (even though most developers have done a great job offering a Joomla 4 test version for a while - you can read articles about these extensions on the Joomla Community Magazine)

I see you site is online again now... see no need to panic after all. This is why backups are important.
