First of all
Appreciate the comments but I think the point of support is that you guys help us which is the reason people buy premium themes.
Yes, we help our customer to use our product. We answer all questions regarding use of our products. We did not advertise that we will help our customer to modify our product.
Just like when you buy a car, it does not come with modifications, unless advertised.
what is the admin-ajax.php script?
It should be ….admin-ajax.php?action=evolve_dynamic_css
That’s the dynamic css file. You cannot remove it.
I would like to highlight to you again, We can only provide customization that can be done using custom css.
If you need to modify any theme code, Please hire a developer from http://jobs.wordpress.net/ to assist in your customization.
By the way, you can consider using a cache plugin to speed up you site, but your web hosting must have enough resources to run it, or your site will appear slower.
