$id_lang = $id_lang ? (int)$id_lang : (int)Context::getContext()->language->id;
Нов код:
public function getCMSPages($id_cms_category, $id_shop = false, $id_lang = false, $id_shop2 = false, $is_list = false)
{
$id_shop = ($id_shop !== false) ? (int)$id_shop : (int)Context::getContext()->shop->id;

ssh грешка: diffie-hellman-group1-sha1

ssh  [email protected] -p 22 -v

Unable to negotiate with IP port 22: no matching key exchange method found. Their offer: diffie-hellman-group1-sha1

ssh -oKexAlgorithms=+diffie-hellman-group1-sha1 [email protected] -p 22 -v
Тук вече се конектва правилно!

Има и друг вариант

Файл:  /etc/ssh/ssh_config:

Host *
GSSAPIAuthentication yes
KexAlgorithms +diffie-hellman-group1-sha1

Инсталиране,конфигуриране и пренасочване на ssl сертификат от суперхостинг

1. Генериране на nginx файлове от Суперхостинг

cat "Частен ключ (Private Key)" > nginx.key

cat "Сертификат" > bundle.crt
cat "CA-Bundle / Root certificate" >> bundle.crt

На практика bundle.crt, включва "Сертификат" и "CA-Bundle / Root certificate"
2. .htaccess
RewriteEngine On

RewriteBase /
RewriteCond %{HTTP_HOST} !^domain.com$ [NC]
RewriteRule ^(.*)$ https://domain.com/$1 [L,R=301]

3. Nginx

server
{
listen 80;
listen 443 ssl;
server_name domain.com www.domain.com;
ssl_certificate /etc/nginx/ssl/domain.com/bundle.crt;
ssl_certificate_key /etc/nginx/ssl/domain.comg/nginx.key;
if ($server_port = 80) {
rewrite ^/(.*)$ https://profi.bg/$1 permanent;
}

………..
}

4. Reload
nginx -t
/etc/init.d/nginx reload
