Can't uninstall "Package manager" as the link is missing

[charled]

Hello,

I've installed Package manager in Contao 3.5.8 but I would like to go back to the 'old' ER. But the link "Go back to the old client' is missing in Package management. I only got : Upadte Composer, Clear composer cache and Experts mode.

What can I do ?

Thanks.

Hm, indeed. I have created an issue here: https://github.com/contao-community-...ent/issues/286

[charled]

Ok. Thanks.

See http://de.contaowiki.org/Composer/Client#Deinstallation

It's in German, though. Do you understand or should I translate it?

[charled]

I've understood but there is a problem : when I save settings just after checking !composer and unchecking repository, I got a blank page. No way to go back. And blank page too for ~/contao/install.php.

Hi,

enable the error output by adding

$GLOBALS['TL_CONFIG']['displayErrors'] = true; 

to your "system/config/localconfig.php"

More strange :
~/website : blank page - no error displayed
~/website/contao/ : blank page - no error displayed
~/website/contao/install.php : blank page - no error displayed

Okay. What about the error log file "system/logs/error.log"? Is there an entry regarding your last change?

You can also check both the folders directly via FTP:

• system/modules/!composer: there should be a file ".skip"
• system/modules/repository: there should be no ".skip" file

Line 70 is :

You can also check both the folders directly via FTP:

• system/modules/!composer: there should be a file ".skip"
• system/modules/repository: there should be no ".skip" file

Both ok

Try to add a new file ".skip" in the "system/modules/syncCto" extension folder. Do you still get the blank page then?

[charled]

Still blank.

To test, I moved the .skip file from !composer/ to repository/ and the site is accessible again.

[xchs]

Yeah, there may be other resources that trigger an error.

However, I still wonder why you get a blank page at all, although you have enabled the error output in the localconfig file.

See http://de.contaowiki.org/Composer/Client#Deinstallation

That can't really work, can it? If you disable the composer client you also disable the autoload.php which will result in the errors described by him.

I think you actually need to disable all extensions, except the core ones - or use the coreOnlyMode.

[Spooky]

imho this is the correct way:

1. Remove all installed packages in the package manager and run a package update^{1 2 3}
2. Delete /system/modules/!composer and /composer
3. Enable the Extension Repository module in the system settings
4. Reinstall all (available) Extensions via the Extension Repository

¹ Don't do a database update afterwards - or at least don't drop any tables (yet)
² If you are not able to access the package manager anymore, you need to delete or disable all extensions manually
³ This step is needed to avoid any problems with loaded extensions that depend on autoloaded classes after you disable the composer client and to avoid any problems with extensions, that are only available via composer

That can't really work, can it?

Idk. Anyway, that was exactly what the core developer has recommended some time ago. See https://community.contao.org/de/show...l=1#post347266

And there you will find also an answer for your current ticket: https://github.com/contao-community-...ent/issues/286

Wir werden die Option "zur alten Erweiterungsverwaltung zurück kehren" wird ohnehin entfernt.
Warum? Weil diese Option nur funktioniert, wenn Composer auch richtig funktioniert. Und in der Regel will man ja zurück, wenn Composer nicht funktioniert.

Added my 2 cents there as well

[charled]

Ok. So If I understand well, the function was removed as it was not working so well as said here: https://github.com/contao-community-...ent/issues/232

So I'll try manually.

Thanks for your help.

I have added a proper Wiki entry here: https://github.com/contao-community-...ki/Switch-back
