Thanks for updating the thread.
Somewhere down the line we all started as a beginner in any field that interest us that also includes web development. However, the support team at Themeco is there round the clock to help you with the issues so that you can have a great presence on the web.
X Theme, Cornerstone are indeed cool tools that will help you to design the layout. It's our endeavour that customers have seamless experience while using X and Cornerstone. Most of the time they don't face issues while using our products. However, we also need to understand that customers use X and Cornerstone on a range of hosting configurations. Sometimes, because of incompatible configurations, customers may face issues while using X and Cornerstone. You can take a look at the recomended hosting configuration laid out by the WordPress community here (https://wordpress.org/about/requirements/). Something we see regularly is not running the recomended version of PHP and limited memory.
Let me explain the logic behind point number 7 and 8. The reason why we are trying to reset .htaccess file is to regenerate a new .htaccess file that will have updated permalinks structure. On the other hand increasing memory limit ensures that the application has enough memory available to execute the scripts. To rename .htaccess file you will need FTP login. On the other hand to increase the memory limit, you can ask your hosting provider to do it for you.
In case problem is still there, please share website admin and FTP details for us to take a closer look.
