* I fixed the lock out, by deleting the bullet proof security plugins .htaccess
file, then deleting in uploads the ithemes security plugin, then have to reconfigure
everything again in the .htaccess file
worked for a few hours then back again.
also tried increasing php memory in wp-config and php.ini but this did not help.

* I’m getting the same problem on a multisite set-up, so every time it brings down
the whole network. Not very happy. And it’s not the first time either
I’ve spent
a couple of hours trying to get to the bottom of the problem, but no luck

* Generally there is an error reported in the web server error_log that helps in
determining what is causing the internal server error 500.

* ok all i can figure from the error_log is that this plugin is causing the error

* Please post the content of your .htaccess file while having this problem.
And
also let us know what Apache web server version you are using.

* I no longer have the .htaccess content that caused the error, but by a process
of elimination, I narrowed it down to banning ip addresses in the hack repair
section.
I have now stopped ithemes security from updating my htaccess file

* It would be interesting to know what Apache web server version you are using.
* Do you remember whether you had IP addresses listed as banned in IPv4 and\or
IPv6 format ?
* IPv4 = xxx.xxx.xxx.xxx(/xx)
IPv6 = xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx(/
xxx)
* _Anything between () is optional._
* If your issue is solely caused by the IP addresses listed in the **Ban Hosts**
setting you can prevent any IP address being added automatically to this setting
by disabling the **Blacklist Repeat Offender** setting in the Global Settings
section.
This would also allow you to enable the **Write to Files** setting
again without a chance of the issue reoccurring.
* There seems to be another topic where iThemes is investigating this issue.

* Server version: Apache/2.2.15 (Unix).
I can’t recall seeing the IP address entries
in the htaccess files, but in the settings they appeared to be normal

* Where normal = IPv4 ?
* For every ip address listed in the **Ban Users** setting the following lines
are normally added to the .htaccess file:
* ```
# Ban Hosts - Security > Settings > Banned Users
SetEnvIF REMOTE_ADDR "^196\.163\.172\.21$" DenyAccess
SetEnvIF X-FORWARDED-FOR "^196\.163\.172\.21$" DenyAccess
SetEnvIF X-CLUSTER-CLIENT-IP "^196\.163\.172\.21$" DenyAccess
Require all granted
Require not env DenyAccess
Require not ip 196.163.172.21
Order allow,deny
Allow from all
Deny from env=DenyAccess
Deny from 196.163.172.21
```
* The above example is an IPv4 address example which I expect to work just fine.
However it seems there is an issue with IPv6 support in combination with Apache
2.2.x
IPv6 support was added to the plugin in the latest 5.3.0 release. So if
your issue started after updating from 5.2.1 to 5.3.0 there is a good chance
the IPv6 support is causing you trouble.
* Unfortunately there is not much info in the [other topic](https://wordpress.org/support/topic/ipv6-support-follow-up)
as iThemes decided to switch to email communication while investigating this
issue …
