Hey. Here is such a problem in the optimization of BM2 and Joomla 2.5:
There are many plugins that optimize and obedyanyayut JSE and DSS and this increases the speed. But when I'm trying to do with BM2, you are continually Here is such a mistake -
Virtuemart.addtocart_popup = '1 ';
Please correct in the new releases this problem. This is very important in building the site. BM2 so and so does a lot of requests and no optimization website end.
Plugins that do not work, but it would be very helpful to add speed
