NopCommerce is not showing any log information on this ajaxfilters issue. Since our site is in development it is not possible to send the url (you need a password). However if you contact me by mail i will send the information
Uncaught TypeError: Cannot read property 'toString' of undefined
RefreshFilters
RequestProductsForSelectedFilters.$.ajax.success
We are having issues with sorting items. We can only make one selection. So if we select a brand we are not allowed to do any additional selection like price, size or whatever.
At this forum a read this was solved with the latest update of the AjaxFilters plugin, but unfortunately downloading it last week. Uninstalling my former installation and Installing it again, it didn't solve our problems.
