 * if you have ftp access, log in and disable/ remove your plugins (bac them up 
   to your computer first though!)
 * both the errors come from plugins, so let us know if you can login after the 
   plugins have been removed

 * Using ftp or the file manager provided by your host change `/wp-content/plugins/
   wp-file-upload` to `/wp-content/plugins/wp-file-upload-old`

 * Worked perfectly! So, does this mean I have a corrupted plugin? Should I deactivate
   all and reactivate one at a time to find the culprit? Thanks!

 * The wp-file-upload was the bad plugin. You should delete it and upload it again
   to see if it works.
 * Many times you can find errors with this.
