Apache Error - AH00124: Request exceeded the limit of 10 internal redirects due to probable configuration error

Question

I have checked my Apache error log and found the following errors:

[Tue Mar 13 05:04:47.855612 2018] [core:error] [pid 18177] [client xxx.xxx.xxx.xxx] 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.

This is a copy of my .htaccess file:

## EXPIRES CACHING ##
<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType image/jpg "access 1 year"
ExpiresByType image/jpeg "access 1 year"
ExpiresByType image/gif "access 1 year"
ExpiresByType image/png "access 1 year"
ExpiresByType text/css "access 1 month"
ExpiresByType text/html "access 1 month"
ExpiresByType application/pdf "access 1 month"
ExpiresByType text/x-javascript "access 1 month"
ExpiresByType application/x-shockwave-flash "access 1 month"
ExpiresByType image/x-icon "access 1 year"
ExpiresDefault "access 1 month"
</IfModule>
## EXPIRES CACHING ##

<IfModule mod_headers.c>
<FilesMatch ".(js|css|xml|gz|html)$">

</FilesMatch>
</IfModule>

# BEGIN WordPress

RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]
# END WordPress

Apache 2.4.27

PHP 7.0.27

Can anyone suggest what i need to change?

Read your message: Use 'LogLevel debug' to get a backtrace. do that, look at the logs, if still unclear, post the debug info in the question. — Nic3500

Your problem caused by this line :

RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L]

So , get this ? out between ^([_0-9a-zA-Z-]+/) and (wp-(content|admin|includes).*) like this :

RewriteRule ^([_0-9a-zA-Z-]+/)(wp-(content|admin|includes).*) $2 [L]

Because , a?c will match against ac as well as a and at your case if a URI is starting with wp-admin it will match in two rules , first with this RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L] and then with this and that why error happened.

Note: clear browser cache then test it .
