Dear Sam,

It took me over a month to find the real problem. I don't know if this is something you can or should test because I don't know if it is specific to my server or not.

However, I am now positive with the origin of my error: it comes from the FTP settings from Joomla.

I had activate the "use FTP" in the configuration of Joomla. And that's why when you uploaded files, they were not owned by httpd.www but by mylogin.users

I have absolutely no idea whether you can check this on config / change ownership when uploading or if it's useful for you to know it. But I wanted to let you know where I stand.

1/ I applied your trick which of course worked
2/ I updated ES which of course overwrote the revision
3/ I had of course the problem all over again
4/ I disabled FTP in Joomla configuration
5/ everything is fine

Best,

Sébastien

Hello Sébastien,

Yep, this is actually a pretty common issue with most Joomla sites IF you have uploaded something when FTP is enabled and try to disable it after that. What actually happened is that when the files / folder is created on the site (with ftp enabled), the ownership would be the ftp user. If you later switch the FTP mode off, then Joomla wouldn't be able to delete / create the necessary files since the initial files / folders were created by the ftp user.

Most hosting company comes with a "Reset permission" tool that you can use to reset all permissions.

Well the thing is my issues shown up despite I did not change my configuration… FTP mode was up since the beginning… I did not change anything. In fact, everything is fine since I turned off FTP mode.

Is that possible that installation and image manipulation are not made with the same function, so that folders were created in FTP mode (so with user permissions) when image upload is done otherwise (so with apache permission) and that's what caused the problem? (not that I really care since it's resolved now… I'm just concerned one might have the same issue, so I'm looking into identifying this thoroughly with you so you can decide if you need to take actions or not! )

Hm, it shouldn't really be the cause of the folder creations because as long as the "php" script is creating those folders, those ownerships would be depending on which user runs the webserver (Unless your hosting provider runs on suPHP)
