Hi there,
After further check on this issues, seems like there are issues on this two modules as you can see here
http://take.ms/iKDGV. I have disabled them and it should works fine now.
If you required them on your site, it would be best if you can consult with them regarding this issues and point out to them that we are no longer EasyblogRouter as our router class and we are using EBR class on our latest version.
Thanks for your understanding.
