I uninstalled recache from the command line and flarum broke

In my logs I get this error:

I tried to clear my cache with:

ubuntu@ip-172-31-44-60:/var/www/seekadventure.net$ php flarum cache:clear
PHP Fatal error: Trait 'Reflar\ReCache\Database\ReCacheTrait' not found in /var/www/seekadventure.net/vendor/flarum/core/src/Database/AbstractModel.php on line 31
ubuntu@ip-172-31-44-60:/var/www/seekadventure.net$

The normal clear cache isn't working...

ReCache modifies some Flarum files when it is installed. I think what you can try to do is remove vendor/flarum/core and run compose install so that the files are reset to their original code.

datitisev any risk on messing anything more up with this?

isn't the point of having a "modular" extension system with flarum supposed to be that the core product is separate to extensions?

doesn't an extension which modifies core flarum files kind of break this model?

datitisev

MikeJones Messing up what? You'd be installing vanilla flarum/core with no recache modifications.

MikeJones

datitisev OK cool, I just jumped in and did it and my site is back up and running!!

Thanks for the help!

The odd thing is it still shows that ReFlar ReCachedev-master is still enabled...

I wont touch that plug until Kyrne is back online again lol

MartinJD Some changes to core files were required for it. There are other ways to do this, one of which is replacing single files (not physically, but in composer's eyes) that would automatically revert to the original - recache did not go with this method.

Not everything can be done without changing some core stuff - my maintenance extension also changes one file (but doesn't have this error).
