your using a 3rd party OPC extension -- ask the developer

the update call gives a 500 server error

"NetworkError: 500 Internal Server Error - https://buyonlinefragrances.com/index.php?option=com_virtuemart&task=updateproduct&ajax=1"
index.p...&ajax=1
POST https://buyonlinefragrances.com/index.php?option=com_virtuemart&task=updateproduct&ajax=1
   
500 Internal Server Error

Developer is not responding so no other solution?

First publicise the dev name so others can learn by your experience of them

2nd. your really not helping yourself by try to build/debug a site with SEF on, plg_jchoptimize on etc etc

these are things you try when you KNOW the site is finished and working

Using Joomla 3.4.1 and VM 3.0.6.4
Product quantity inputbox on frontend  shows NaN when first add products with the "+" sign and then click "-" sign till you get 0 (NaN) quantity.

I was using my custom templating in mytemplate/html/com_virtuemart that's why I had some sort of javascript error, just deleted that folder and everything is back to normal
