No sidebar & can’t login to JetPack

Ever since I’ve upgraded JetPack and www.ads-software.com, I have gotten two main issues on my website https://northsouthblonde.com

1) The sidebar is missing. Strangely enough, I am still generating ad revenue from my ad widgets located in my sidebar. There is just a blank space where my sidebar used to be.

2) JetPack will not allow me to sign in. It says I’m connected, but when I go back to my dashboard, it continues to prompt me to log in.

*I’m not sure if these two issues are related*

Here’s what I’ve tried:
– Deavtivating all plugins (Didn’t do anything)
– Restoring www.ads-software.com’s default Theme (& plugins deactivated). Still no sidebar and no jetpack login success.
– Removing Jetpack from my Cpanel and reinstalling it (issue remains the same).
– BlueHost technical support had unblocked my server to allow jetpack to communicate. Still nothing.

My issue remains unresolved. At this point, I am backing up my files ready to start a new domain. Help is much appreciated at this point! Please help!
