Development only allows to perform testing without closing out public access to site and without installing product locally. This feature helps to solve the issue of collective access to a single product installation. This option is also useful when several developers need to have a custom public product instance for testing purposes.

Selecting database

MySQL database have available UTF-8 encoding. If you choose to install UTF-8 version, mark the Install with UTF-8 encoding. However, selecting UTF encoding requires the mbstring PHP module to be installed. You can verify the availability of this module by examining the contents of php.ini file:


Attention! From 1 January 2017, Bitrix24 has limited support of products using Oracle Database and MS SQL Server: clients cannot download product updates and use new product versions.

Site encoding

Mark the option to use the UTF-8 encoding for your Bitrix24 instance.

Presently, HTML document ending has two options between WIN-1251 and UTF-8.

Using the encoding WIN-1251 is appropriate with old versions of MySQL (before version 4.х), which worked with UTF-8 incorrectly. These drawbacks are not present in modern MySQL databases.

To correctly support the UTF-8 encoding, mbstring module must be installed in PHP. To verify it, php.ini file in PHP settings must contain the following:


It is recommended to use UTF-8 encoding for proper versatility and full applicability of existing characters.
