Always use the latest stable version of Joomla. To ensure full compatibility verify that your server/hosting service meets the PHP requirements.

PHP Settings

The minimum and recommended PHP requirements*:

• PHP 7.0.x, PHP 7.2 or PHP 7.3 (64 bit version)
• MySQLi 5.5, 5.6 or 5.7 (suggested)
• upload_max_filesize = 4M (or more)
• memory_limit = 128MB (256MB or more suggested)
• max_execution_time = 180 (300 or more suggested)
• PHP upload_max_filesize = 4M or more
• Magic Quotes GPC - Off
• cURL library - your server must work with curl or url_fopen.
• OpenSSL - must be enabled.
• PHP file_get_contents() function - must be available/unlocked.

Note: Support for PHP 5.4 and PHP 5.5 ended, also PHP 5.6 is only partly supported.

* Those values can be changed in php.ini or .htaccess file. Please contact your web hosting service provider to be sure that your server complies with the requirements or to ask them where/how to change PHP settings. There are some less demanding situations where Template and SP Page Builder will perform quite well in weaker PHP settings.

Remember to restart Apache (localhost only) after configuration changes.
