LiveAgent Requirements

Since 1st October 2022
- we will stop supporting PHP 7.4 / PHP 8.0 (we will use PHP 8.1) 
- we will stop supporting MySQL (we will keep support for MariaDB only)
Before you order LiveAgent, please check if your server meets the following requirements:
  • PHP7.4 or higher (PHP8 is also supported)
    - with extensions:  MySQL PDO or MySQLi, gd2, exif, iconv, mbstring, php-json, php-xml, PHP5-CURL package, bcmath, fileinfo
    - required cron PHP max_execution_time set to 0,
    - recommended minimal memory_limit 64MB, recommended 128MB,
    - recommended web PHP minimal max_execution_time 30 seconds,
    - enabled php session,
  • MariaDB 10.2 or higher (recommended MariaDB 10.4)
    In case of MariaDB 10.6 you need to disable innodb_read_only_compressed which is enabled by default.
    Fully supported are also MySQL 5.7 and Percona 5.7 (or higher). Here you can read how you can easily check your version.
    • without SQL mode ONLY_FULL_GROUP_BY
    • also, make sure that database user has all privileges for database granted!
  • Web server Apache, Nginx or any other, which supports PHP, .htaccess and mod_rewrite
  • Operating system any Unix like, Windows or Mac (basically all operating systems are supported if the operating system supports the installation of web servers)
  • Disk space - absolute minimum 300 MB, plan ahead space required for your data (all emails, attachments, chats, tickets are stored in the database)
  • cUrl version 7.39 or higher (older versions cause a problem when connecting to our license server)
  • SSL -  since version 5.25 it's mandatory to use SSL certificate and https://
  • WkHtmlToPdf tool (this is only required for one specific LiveAgent feature to work properly, exporting tickets to PDF. Detailed info here.)
  • ElasticSearch
    Using ElasticSearch for full-text search in LiveAgent is recommended for customers with high volume of the tickets in their installation
    • If you're using ElasticSearch
      • only versions 6.x are supported up to LiveAgent version 5.23.14
      • versions 6.x - 7.10.2 are supported in LiveAgent versions 5.23.17 - 5.23.99
      • only versions 7.x are supported from LiveAgent version 5.24

Recommended Browser requirements:
LiveAgent runs on all major browsers. For the best security and functionality, keep your web browser up to date. All modern browsers should update automatically. The minimum browser requirements are:

  • LiveAgent admin / agent panel
    • Microsoft Edge - latest two versions
    • Google Chrome - latest two versions
    • Safari - latest two versions
    • Opera - latest two versions
    • Mozilla Firefox - latest two versions
  • LiveAgent widgets and visitor pages
    • We try to keep the backward compatibility of our widgets also for older versions, so your customers will be able to reach your support team even from older browsers. Anyhow, since version 5.26 we no longer support our widgets in IE11 and we recommend using other browsers.
    • In case you observe any issue, let us know via
Recommended setup of server:
- 4 Cores @ 3.2GHZ Turbo
- 8GB RAM (DDR3)
- 2x 128GB SSD raid1
NOTE: The directory, to which you are about to install Live Agent must be available via browser by some  URL address or IP  ( e.g. )
Example configuration
Processor: Intel Dual Xeon E5-2620 Hexa Core (Romley) 2.0Ghz per Core
Processor: Intel Dual Xeon E5-2620 Hexa Core (Romley) 2.0Ghz per Core
NOTE: The application server and database server must be running on separate machines in this case.
NOTE: We do not recommend GoDaddy's shared hosting due to their weird fast_cgi limits that may cause the entire site go down temporarily if the limit is exceeded. Exceeding that limit results in having the error logs full of the following log entry:
fcgid:warn] (9)Bad file descriptor: [client] mod_fcgid: ap_pass_brigade failed in handle_request_ipc function
