Update WordPress to 4.5.2
Use FTP to login to your web server.
If there is already a copy of alora theme in your wp-content/themes/ folder you should delete it via FTP.
Then use FTP to upload a fresh copy of alora to your wp-content/themes folder
Don’t use overwriting on FTP unless you are sure that your FTP connection is stable.
If not, it will result in mixing old with new content, which could be the cause of your fatal error.
I have WordPress 4.5.2 and Alora 2.8.0 and Theme4press 1.3.5 and reduxframework 188.8.131.52 working properly on my localhost.
Once you get them working, then you enable other plugins, one at a time,
