the button in blue makes a message appear in red (horatio)

Hello there On Joomla 3.9.26 stable i clicked on the blue Button up in the Image and then the red button above appeared.

I googled the error-message. I found something for joomla 1. and 2. but that does not help me.

I am using:

  • Linux Raspberry 5. Firmware
  • mysql
  • mariaDB
  • php 7.3
  • Apache 2.4 (rasp)
  • Joomla 3.9.26 Stable (armani)
  • Joomla Platform 13.1.0
  • Mozilla Firefoxy 84

does Joomla need some rights? the Joomla folder on the raspi is chmod 755 according to an instruction. (I will check but I think it was Joomla forum).

Thanks in advance - have a great day or night.

PS: I followed folder permission here: and I found this problem on Folder Permission which should be writeable:

my not writeable folders

And the user group is root root, i want to change this for my user name and joomla account is kamin-user. I will follow this link.

  • Thanks for the thumbs up. I followed the link instructions. When my Joomla Account is kamin-user i might need www-data rigths (not so sure about that.) So chmod -R 775 and chown -R kamin-user:www-dat is what i am trying next – kamino Apr 21 at 16:30

So this is how i got green flags again.

  1. first I added a user lets call him kamin-user

sudo adduser --home /var/www/joomla --shell /bin/bash --no-create-home --ingroup www-data --ingroup ssh kamin-user

  1. second I made a ownership with kamin-user and www-data important is only the www-data on second place (try and error) you can do root:www-data

sudo chown -R kamin-user:www-data joomla/

  1. third I did modify the permissions. (755 did not work)

sudo chmod -R 775 joomla/

Lastly i don't know why this is needed and if that is a good setting. I will choose any answer that explains that a little. Or close it with this answer with in 2 Weeks.
