I was using wordpress 3.8, I upgraded to 4.5. The sire worked for a couple minutes but now it is getting a 500 error, with this as the error log
[Sun Aug 07 17:33:11 2016] [alert] [client 208.115.113.82] /home/nesainc/.htaccess: Invalid command 'Add', perhaps misspelled or defined by a module not included in the server configuration
Any help would be appreciated.
