Upgrading Drupal

Before I post a bug issue, I would like to try to find help in the forum firest.

I have upgraded drupal 7.41 to 7.50 on my production system. But then latter come an issue of content permission. I have a role that set to allow a user edit his own content for a certain content type. But the role is not working anymore. Previously before upgrade, it works. But after upgrade, it doesn't.

Hi All,

We're trying to migrate an old Drupal 6 site with tons of custom content types over to Drupal 7. Needless to say, this has been a very difficult process.

I installed a Drupal 8 site in June (sfwalk.net) as a way of learning the platform, and just tried to follow this procedure to update to 8.1.8.

I follow the procedure exactly, including copying over my existing settings.php file and setting permissions.

I get the following messages from Drush:

Hi,

Hi guys.

I have been consistently getting this error when making minor updates for Drupal from 8.1.5 to 8.1.6 to 8.1.7 to 8.1.8.

solidtra@phx15 [~/public_html]# drush pm-update drupal
Update information last refreshed: Mon, 08/01/2016 - 14:38

Drupal 8.1.7 8.1.8 Update available

I just update my drupal from 8.1.7 to 8.1.8, and after switching the files, as the process is written, I tried to run the update.php, but then that message appeared :"The website encountered an unexpected error. Please try again later." I tried to make the changes in the settings.php, but it didn't do anything.
I use OVH to and filezila to host and import my files and website.

I would gladly appreciate if you could tell me what is wrong with that ?
Thanks in advance
