Upgrading Drupal

I manually upgrade my drupal site, i'm sure that the patch'es procedure is correct but when i try to reach my site, i have this error in response:

403
Forbidden

You don't have permission to access /mysitename on this server.

I check the htaccess , but i don't know what the problem is. I check all the permissions in my Centos virtual machine but nothing. Can you help me guys?

Hi All,

When I am trying to upgrade my site from Drupal 7.44 to 7.52, I am getting this error when I visit the url admin/reports/status
Fatal error: Call to undefined method DatabaseConnection_mysql::utf8mb4IsConfigurable() in \modules\system\system.install on line 549

When I googled I got lot of answers, I tried out following things in my end

- Added following configurations to my.ini file

I just completed a manual upgrade of drupal 8.2.2 to 8.2.3. Now in the reports section I see the following error:

Mismatched entity and/or field definitions
The following changes were detected in the entity type and field definitions.

Yesterday when I upgraded my Drupal site from 7.50 to 7.52 with GIT i got a merge conflict in includes/locale.inc.
This is how I normally do the upgrades: I have 2 remotes one for drupal (renamed to drupal) and one for my site (origin).
Whenever there is a security update I fetch my drupal remote and merge it into my repo (git fetch drupal, followed by git merge 7.52, in this case).

Hi Everyone, I encountered a situation that is driving me crazy, so here the problem is:

I have a drupal site that needs update on the core and modules, but it is currently running on our live server, since my knowledge is limited with drupal, I would like to perform the update on a dev server first. So I copied all the files and databases and all that:

I am about to conduct an update of Mysql but a drush report shows I ned to conduct a Drupal core update.
Is it ok to do the core update first or after the Mysql upgrade?
Here is the drush report. The modules are not supported I guess because of Mysql issue
Thanks any advice here.
