 After installing the SiteGround toolkit "Secure Admin" and entering my IP address, I get a 500 error when attempting to access the administrator panel. The error log entry is: Thu Apr 13 07:46:16.536240 2017] [core:alert] [pid 19223] [client 98.203.125.199:34514] /home/msneadfa/public_html/administrator/.htaccess: RewriteRule: bad flag delimiters

Falling back to the basic htaccess eliminates the problem. Any ideas on which of the administrator rewrite rules is causing the problem? There are 10 occurrences in my generated htaccess. I've attached the generated file below

Additional info: I found that SiteGround implements their secure admin by adding "deny from all" and "allow from my.ip.0.0" to the .htaccess file in the administrator directory. Removing those directives and restoring the full generated .htaccess works. Any help to resolve the conflict would be appreciated.

SiteGround just found the error was in their htaccess file and fixed it. You may close this ticket.
