Replace with your Apache/IIS user and replace with the Apache/IIS user’s group
i.e: ubuntu will usually have www-data as both and so the command for ubuntu would likely become: sudo chown -R www-data:www-data .
Then, navigate to your config.php file and find the default_permissions array.
Replace the values there with:
‘dir_mode’ => 1517,
‘file_mode’ => 420,
‘user’ => ‘’, Again, Replace with your Apache/IIS user’s name
‘group’ => ‘’, and Replace with the Apache/IIS user’s group
using ubuntu as an example again, the lines will become:
‘dir_mode’ => 1517,
‘file_mode’ => 420,
‘user’ => ‘www-data’,
‘group’ => ‘www-data’,
After this, redownload the Langauge package, re-upload it to the CRM and try to install it again.
You need to start by solving the red alert on the first screen and set a max upload bigger then 6MB (try 100 MB even if it is not necessary now it could be good later)
