No, you don’t need to pay any additional fee to use our theme or plugins that come bundled.
But one recommended (not required!) plugin causes the problem – Massive addons for VC. It breaks the Visual Composer editor.
So, you may try to follow the plugin author instructions and do the following:
First of all, please increase the memory limit do at least 128M (256M is recommended).
Then, please make sure that your server is not using mod_security or FastCGI handler for PHP. If it is, you need to contact your hosting provider and ask to increase the maximum body length value.
Or disable this plugin and don’t use its elements because this plugin offers just additional elements to build the page.
You need to buy this plugin only in case you want to get the individual support from the plugin author.
