Hi webdesign4,

Did you download a copy of concrete5 from concrete5.org or from GitHub?

The version of concrete5 available on concrete5.org includes third party libraries and the version on GitHub does not.

To download third party libraries, you will need to install Composer.

After installing Composer, run "composer install" in the concrete directory of your site (concrete\composer.json).

hi, thanks for the first
i take it only from concrete and the update is from the system who tell me i have an old version 5.7.13 and i can upgrade to 5.8 an after i do this i get the error

now i get this
Invalid "update.core" defined. Please remove it from /kunden/296908_83324/webseiten/application/config/update.php.

@webdesign4

I wonder if the update didn't complete or download correctly.

Do you have a site backup from before you tried to update?

i know, but i dont have one my error - i try im moment to change per ftp some things.

i dont fixed it , i crash the site and make a new installation

i fixed it, i remove the upgrade.php and it works ---- i am happy
Thanks
