Hello,
Thanks for updating, glad that your issues are resolved now. Please find the response to your inquiries below:
1 The functionality to attach files from local pc to comments comes only with the version of Komento pay?
Yes, that is correct.
2 If so, I want to confirm to the value of 25 dollars pro..son version? This payment is made only once?
The $25 is for 1 year worth of subscription and updates. Once your subscription expires, you will need to renew at 20% discounted rate to get an additional year of support and subscriptions.
3 After making payment, what should I do to have the functionality to attach files within the Komento version that I have assembled on the site?
Download the Pro version, upload and install it on your Joomla! site
