Hrm.. well, i’d really like to help, but i’m not sure i understand what exactly the issue you are having is. Like what do you mean by “crash”. Does the site simply fail to load, loads a blank screen, loads garbled, or jumbled text etc…
Unfortunately, without more information, there’s really no way for me to tell what’s causing the issue.
If you are having issues with the plugin causing stability with your entire site, that’s a cause for concern, you should really put your site into debug mode, and log the exact errors, and report them. My guess, is that something else on your site, perhaps a custom theme, or other plugin is causing a conflict. Detailed debugging output will go a long way for helping us resolve that issue.
If you have spare time, go through a disable your plugins except NGS Same Integrator, and one by one enable them and check the site until it breaks, that should show you what plugin is conflicting.
If however, the site still has issues once all plugins are disabled, and a custom theme is in use, you can almost bet that there is a funciton within the theme that has the same name of scope of those of this plugin/.
