This option allows you to control whether anything between the standard <?php and ?> tags will be treated as - PHP code by Enano. If this option is enabled, and members of the Administrators group use these tags, Enano will - execute that code when the page is loaded. There are obvious potential security implications here, which should - be carefully considered before enabling this option.
-If you are the only administrator of this site, or if you have a high level of trust for those will be administering - the site with you, you should enable this to allow extreme customization of pages.
-Leave this option off if you are at all concerned about security – if your account is compromised and PHP embedding - is enabled, an attacker can run arbitrary code on your server! Enabling this will also allow administrators to - embed Javascript and arbitrary HTML and CSS.
-If you don\'t have experience coding in PHP, you can safely disable this option. You may change this at any time - using the ACL editor by selecting the Administrators group and This Entire Website under the scope selection.

This version of Enano is designed only for testing and evaluation purposes. It is not yet completely stable, and should not be used on production websites. As with any Enano version, Dan Fuhry and the Enano team cannot be responsible for any damage, physical or otherwise, to any property as a result of the use of Enano. While security is a number one priority, sometimes things slip through.
- -Enano has several requirements that must be met before it can be installed. If all is good then note any warnings and click Continue below.
-Now we need some information that will allow Enano to contact your database server. Enano uses MySQL as a data storage backend, - and we need to have access to a MySQL server in order to continue.
-If you do not have access to a MySQL server, and you are using your own server, you can download MySQL for free from - MySQL.com. Please note that, like Enano, MySQL is licensed under the GNU GPL. - If you need to modify MySQL and then distribute your modifications, you must either distribute them under the terms of the GPL - or purchase a proprietary license.

This option allows you to control whether anything between the standard <?php and ?> tags will be treated as + PHP code by Enano. If this option is enabled, and members of the Administrators group use these tags, Enano will + execute that code when the page is loaded. There are obvious potential security implications here, which should + be carefully considered before enabling this option.
+If you are the only administrator of this site, or if you have a high level of trust for those will be administering + the site with you, you should enable this to allow extreme customization of pages.
+Leave this option off if you are at all concerned about security – if your account is compromised and PHP embedding + is enabled, an attacker can run arbitrary code on your server! Enabling this will also allow administrators to + embed Javascript and arbitrary HTML and CSS.
+If you don\'t have experience coding in PHP, you can safely disable this option. You may change this at any time + using the ACL editor by selecting the Administrators group and This Entire Website under the scope selection.

This version of Enano is designed only for testing and evaluation purposes. It is not yet completely stable, and should not be used on production websites. As with any Enano version, Dan Fuhry and the Enano team cannot be responsible for any damage, physical or otherwise, to any property as a result of the use of Enano. While security is a number one priority, sometimes things slip through.
+ +Enano has several requirements that must be met before it can be installed. If all is good then note any warnings and click Continue below.
+Now we need some information that will allow Enano to contact your database server. Enano uses MySQL as a data storage backend, + and we need to have access to a MySQL server in order to continue.
+If you do not have access to a MySQL server, and you are using your own server, you can download MySQL for free from + MySQL.com. Please note that, like Enano, MySQL is licensed under the GNU GPL. + If you need to modify MySQL and then distribute your modifications, you must either distribute them under the terms of the GPL + or purchase a proprietary license.
