Wordpress in It's own directory

[ibbookies]

I'd installed my wordpress in Method II (With URL change). Everything goes well except when accessing some dashboard that needs wp-json like widgets and plugins dashboard like really Simple SSL , Code Snippets. Is there a way to fix this ? I had tried to reinstall those plugins but failed.

plugins installed :

• Asset CleanUp: Page Speed Booster
• Code Snippets
• GA Google Analytics
• Insight Core
• LiteSpeed Cache
• Manage Notification E-mails
• Popup Maker
• Really Simple Security
• Stop User Enumeration
• Wordfence Security
• WP Mail SMTP
• WPBakery Page Builder

.htaccess on SITE ADDRESS folder (Site Address URL) :
# Any changes to the directives between these markers will be overwritten.
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

.htaccess on Wordpress Address folder ( main wordpress file in folder "mywordpress" )

# Any changes to the directives between these markers will be overwritten.
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteBase /mywordpress/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /mywordpress/index.php [L]
</IfModule>

# END WordPress
