Cant log into back office 1.6.1.22

[RiaanP75]

Everytime i try to log into my back office it takes a long time and then it just shows the front of my website with two errors, is there anyone that can assist me to resolve this problem?

 

I have cleared the cache and i have also cleared the browser, so that is not the issue, 

 

Please see attached photo error 1 is when signing in, and photo error 2  is where it ends up after about 3 minutes,

Did you end up solving your issue?

For me I had to re-enable overrides and fix a file in my error log
