IanM I'm guessing you edited your composer.json entries to * as per the upgrade guide.. But, by the looks of things, your composer.lock file is outdated.

Follow this exactly

Edit your composer.json, change "flarum/core": "¹.0", to "flarum/core": "0.1.0-beta.16",
Run composer update -W
composer remove antoinefr/flarum-ext-online
Edit composer.json, change "flarum/core": "0.1.0-beta.16", to "flarum/core": "¹.0",
Run composer update -W

So long as the rest of your required extensions are 1.0 ready, you'll be upgraded

this is the right procedure .. Correct

IanM I removed Online Success and

IanM When the time comes to upgrade your forum to 1.0, you'll need to remove this package prior to upgrading, using the following command:

composer remove fof/console

./composer.json has been updated
Running composer update fof/console

[deleted] Right, where are you along the steps I gave you?

[deleted] and All css are lost please help last time

[deleted] ok, I've reviewed your composer.json you posted above. For the moment ignore the fof/console abandoned message, and continue with my instructions I gave you.

When you've managed to reach the end of those commands, fof/console should automatically be removed, as the extensions that require it for beta 16 drop it for 1.0

IanM 1.0

I updated to 1.0 but css and js all things are lost

[deleted] Ok, then these are the commands you need now:

• php flarum cache:clear
• php flarum assets:publish

[deleted] I'm glad you've managed to upgrade sucessfully. Enjoy!
