error on ehcp after deleting domain

I got an 500 Internal Server Error after I try to delete a domain in my ehcp.

when I look to my error.log in my apache, I got this error :

Request exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRe$

I have tried to add this answers from

but it has the same error....

does anyone have an idea about my case?

thanks in advance ...
