infinite post load stopped working - cant fix it
I think the new jetpacked screwed it up, i had to resort to using default theme setting. Someone helped me with this way back and it worked great (sent some kind of plugin or update pack), but as mentioned stopped working.
I hope you are well today and thank you for your question.
Please make sure you are using latest version of theme and plugins on your site.
This can be due to plugin conflict on your site so please try temporary deactivating all plugins except Jetpack plugin and see whether everything works fine and then enable the plugins one by one to see which plugin is conflicting if any.
