Linux shell tar zcvf bad written broke a folder in my server

Question

I was trying to compress a directory and I missed. I wrote:

tar zcvf wp-content/* 

I don't know what happened. My folder wp-content seems to be fine but the server doesn't work (my website doesn't load). Here the an extract from apache error log:

[Fri Jun 12 16:42:54.034140 2015] [core:error] [pid 6771] [client 172.31.5.225:57994] AH00124: Request exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace.

Is there any way to undo the command I wrote badly? Any help?

edit: the output of the folder where I wrote the sentence
