I am trying to install our live Magento EE site on Wampserver but I am getting a 500 "Internal Server Error" and the below error in my Apache Error Log. I am being told on the Wampsever forum that I "may" have missed one or more Magento prerequisites seen in the link below but it "appears" I already met all the prerequisites?

So what exactly is .htaccess: Invalid command 'ess.swp'?

5] [core:alert] [pid 7960:tid 848] [client] C:/wamp/www/shopcandelabra/.htaccess: Invalid command 'ess.swp', perhaps misspelled or defined by a module not included in the server configuration, referer: [http://localhost/][1]

    You might need to update the question with your. htaccess file code for better understanding your problem.

Solved! I had to comment out the line with "ess.swp" in my .htaccess file. I also had to comment out these lines (ExpiresActive, ExpiresByType) as they were also generated errors in the Apache Log.
