Fix for Encoding Issue and missing features

Following fixes are done in this version - 

1. In the chat between buyer and bidder the send function is not working. If you click Send the button, nothing happens. 
2. In ​​invoices, when clicking on the Pay Now button nothing happens. 
3. The header has charset UTF-8, but the files were not saved in that encoding. 
4. The list view of products that appear on the home page doesn’t work, it’s static and has to be manually added. It’s just a layout without functions.
5. Currency must be displayed with mask (0,00). Some are appearing differently than that
6. Apparently the charset is influencing CSS, system must be checked.


Regarding 3,4 and 6 - seems like those issues was not in our code that we delivered. I believe you checked demo which was working just fine. and we applied some of your translation to our code - which worked just fine, we had no encoding issue with our files. 
To fix the issue - I had to go through your translated files and copy those translated text into our files.
