After changing wp-content directory, you need to logout and login again. If issue is still present, then check the following

1. Under iThemes security > settings > Global Settings > Path to Log Files
2. Under iThemes security > settings > Database Backups > Backup

Location

If you find wp-content directory instead of app-data directory in those two paths, just click on restore default location button. Logout and login again, then see if you are able to access media library.

We have been using this feature on several websites without any issues except those mentioned above.

If,for any reason, the following lines not written by iThemes Security, then wordpress unable to find exact location of media library. Make sure the following present in wp-config.php file.

//Do not delete these. Doing so WILL break your site.
define( ‘WP_CONTENT_URL’, ‘http://youtdomain.com/app-data’ );
define( ‘WP_CONTENT_DIR’, ‘/home/your-cpanel-username/public_html/wordpress-directory-name/app-data’ );

/home/your-cpanel-username/public_html/ is document root, change this path if your server having a different path.

Method I:
Contact hosting service provider where MySQL version is higher than 5.5.40. Ask them to load atleast MySQL v5.5.40.

(or)

Method II: Temporary solution
Edit line no.70 in system.php file at
wp-content>>plugins>>better-wp-security>>core>>content>>system.php

After finding the above system.php file edit line no.70 like this:

mysql_get_client_info() to mysqli_get_client_info()

Note for method II:
Whenever a plugin updated, the above process need to be repeated again

Pinboard comes with 18 templates. All these templates fall into four categories: Blog, Static Pages (content), Portfolio, others. You are selecting blog templates for static pages.

I’d like to have a left sidebar on a few of my pages (not all though)

1. You have to select one of the templates having their name content. Here for your requirement, you need to select template either sidebar/content or sidebar/content half for required pages.
2. Theme Options>>Layout>>Content Columns>> Select 3 or 4 from dropdown
3. Add atleast one widget in one of the sidebar widget sections: Sidebar Top, Sidebar Left, Sidebar Right, Sidebar Bottom

Now your required page layout appear on the front end.

Is it possible that htaccess from root folder have some conflict with this new installation

It’s not a conflict, it’s working fine as expected. It happens with multi-domain hosting plans, where all Addon-Domains and sub-domains folders have their place within the root dorectory/folder.

@dwinden

Ok, so that confirms there is some problem with the content of the .htaccess file in the root.

I don’t think there is a problem with above set of rules on htaccess.

Let us assume, we have a multidomain hosting (shared or similar) with root domain PrimaryDomain.TLD. Now the default directory for this primary domain is root where index.php reside. So, htaccess file will be generated in root. Since htaccess file in root directory which contains rules that restrict install.php (wherever it exist, since htaccess is in root), it will not allow new installations for either Addon or sub-domain.

We have three best possible ways to avoid this.

1. Install PrimaryDomain.TLD in a sub directory like blog, eng, index, home etc. So that all files including index.php and htaccess file will be in that sub-directory. Then primary domain url will be PrimaryDomain.TLD/blog or other. Now no rules from root will restrict addons and sub-domains installations.
2. Install PrimaryDomain.tld as usual, but remove the rules that restricting new installations.
   Or disable the Protect System Files setting in the System Tweaks section on the iTSec plugin Settings which write similar rules on .htaccess in the root directory. After new installations complete, enable the previous option in primary domain.
3. Never try to rename .htaccess file in the primary domain if it has significant traffic. Instead put your site in maintenance mode and change whatever you like in .htaccess. After successful new installations for addon or sub domains, revert whatever changes made in .htaccess file. Next disable maintenanace mode for primary domain

Important Note:
If the first method is implemented, then manually add .htaccess file in root directory. And add essential security rules on htaccess like the following one.

# Rules to disable directory browsing
Options -Indexes

So that directory browsing will be restricted.

Once new installations for either Addon or Sub-domains are over, everything work as normal.

.htaccess file protect the directory in which it resides, and all sub-directories within that directory.

Change the status of this thread to resolved, if your issue is over.

I think you are dealing a site which is not enabled by SSL certificate.

#Error Documents
ErrorDocument 404 /404.php
ErrorDocument 403 https://www.mydomain.com/access-denied/
ErrorDocument 500 https://www.mydomain.com/server-error/
ErrorDocument 400 https://www.mydomain.com/bad-request/

The above lines are written by yourself or other user having root access, but not by ithemes security plugin.

If your site is not having any SSL certificate, then change https to http for all instances. Since you uninstalled or deleted ithemes security, and getting 500 – internal server error, there is a greater possibility of misconfiguration in server side script, here it is .htaccess.
