This maybe helpful to others page builder wont load and RSS feed not loading too in home page.
Sometime it happens that we have a lot of template instaled which some of them we dont really use.
Just chose one temp then make a "backup" folder to your template directory and put your non used template there and just left the temp you like.
After that uninstall profiler mod in admin tools modules and clear everything cache, db, js, css etc.
Then that's it! Page builder is back RSS is back site runs smoothly as you want it to be hopefully it will help some one or this thread to actually fix the issues no matter how many modules installed from 3rd party this work on Dolphin 7.0.7 latest.
God Speed to all!!
