Upgrade... broke backend

I managed to break the backend of my site. The front looks great, and works great after the upgrade. I jumped from 1.6.31 to 1.7.7. I used
bin/gpm self-upgrade
The front end works, and no errors are logged! When I run bin/grav logviewer Only errors from before the upgrade show. I then ran a few other commands, cleared the cache etc. Now when I run:bin/gpm index I get nothing. When I visit my webpage/admin also, I get an error:

Server Error

Sorry, something went terribly wrong!

0 - RecursiveDirectoryIterator::__construct(): Argument #1 ($directory) cannot be empty

I do manage to get that error in the log too

2021-03-15 02:26:33 [CRITICAL] RecursiveDirectoryIterator::__construct(): Argument #1 ($directory) cannot be empty

Any help is greatly appreciated. Many of my gpm commands do nothing.

Yes, I did this on a live site. I can restore a back if needed.

Thanks! My webserver is running php8, my local machine is not. When I downloaded the upgraded version, it ran fine on my local machine. So I downgraded the php on my server, and now all is good. Thanks for the help! Also, bin/gpm index is working.

Hmm... I think v1.7 should be compatible with PHP8 and run without issue 🤔
Requirements page says:

PHP 7.3.6 or higher

Maybe some PHP setting is messing up things and this should to be fixed in Grav 😕

Any chance you could compare php.ini files and enabled extensions maybe?

Grav is compatible with v8, but that error can emanate from anywhere - not related to versions or configuration. Do you still have the full error stack?

If you can tell me where to find it, I probably can pull it up. I would be willing to pass it along.

PS - I bumped it back up to PHP8, and now everything seems to be running fine. I think when I upgraded Grav, the plugins didn't upgrade. After dropping back down to PHP 7.4, I upgraded the plugins with the Admin GUI. I then switched PHP back to 8, and all is working like a charm now. So I think some of the errors were plugin related, not Grav 1.7.

They might well have been. PHP errors would usually be in /logs/grav.log.

Here is the first log entry:

Whoo, it's my fault! This comes from a method in the Presentation-plugin that loads up the available themes for Reveal.js. I'll make a note to test it with the latest 1.7-version of Grav Core, and update as necessary. Thanks for the full error-stack, it makes it much easier to trace the source of the problem.

I'm not a dev, so glad I can at least help by posting errors! :) Every little bit helps.
