Products RSS Feed in Litecart 2.1.1

How to make the AddOn compatible with LiteCart 2.1.1 on PHP 7.0 (@ MochaHost)

After installation, ErrorReporter Module, has sent:

Request: GET /feeds/products.rss HTTP/1.1
Client: *.*.*.*
User Agent: Mozilla/5.0 Vienna/3.3.0```

```Warning: Illegal string offset 'en' in ~/pages/feeds/products.rss.inc.php (Line 25)
Request: GET /feeds/products.rss HTTP/1.1Client: 
*.*.*.*
User Agent: Mozilla/5.0 Vienna/3.3.0```
Due to the fact that "english" is disabled as Language, I tryed to change to "italian":

```pages/feeds/products.rss.inc.php:2
$language_code = 'en'; 
=> $language_code = 'it';```
With no success. What to do?

Italian is set by the url, either:

/it/page

Or

/page?language=it

"One step beyond"!
I changed "Vienna" feed reader URL to "http://www.poligrafica.store/feeds/products.rss?language=it" and it recovered the feeds.
But, the feeds are empty. Following is the content of one of the feed from Cached item in "Vienna":

<rss version="2.0">
  <channel>
    <title>Poligrafica</title>
    <description>Poligrafica</description>
    <link>http://www.poligrafica.store/</link>

</rss>```
It seems that <title> and <description> tag are corrupted.

In the code,  at pages/feeds/products.rss.inc.php:20 this should recover the <title> for the $language_code defined

```$output .= '  <item>' . PHP_EOL

            . '    <title>'. $product->name[$language_code] .'</title>' . PHP_EOL```
Is "$product->name" the right way to recover the name of the product in Litecart 2.1.1?

Add-on updated for LiteCart 2.x

Great! I have only italian enabled and it works ok even without language and/or currency specification:

• http://www.poligrafica.store/feeds/products.rss

There seems to be an issue with "Manufaturers", the're not displayed.

@user3549 There are no manufacturers in the product feed.
