Site is not loading .htaccess rewrite rule error. How to fix this ? : The site does not load anymore and in error log file I can see. This happened suddenly after attempting to load files such as video and img.

EROOR messages are :
RewriteRule: cannot compile regular expression '^([0-9]+)\\/([^\\d\\/]+)([0-9]+).**\\/[0-9]+,[0-9]+\\)\\).*\\/*![0-9]+.**\\/\\)``\\)``\\)\\)$'
