Installing TYPO3 CMS 6.2.4

System environment check

TYPO3 is an enterprise content management system that is powerful, yet easy to install.

After some simple steps you'll be ready to add content to your website. This first step checks your system environment and points out issues.

Detailed analysis

PHP Maximum upload filesize too small
PHP upload_max_filesize = 4 MB
TYPO3_CONF_VARS[BE][maxFileSize] = 10 MB

Currently PHP determines the limits for uploaded file's sizes and not TYPO3. It is recommended that the value of upload_max_filesize is at least equal to the value of TYPO3_CONF_VARS[BE][maxFileSize].

Some PHP functions disabled

These function(s) are disabled. TYPO3 uses some of those, so there might be trouble. TYPO3 is designed to use the default set of PHP functions plus some common extensions. Possibly these functions are disabled due to security considerations and most likely the list would include a function like exec() which is used by TYPO3 at various places. Depending on which exact functions are disabled, some parts of the system may just break without further notice.

PHP extension zip not loaded
TYPO3 CMS uses PHP extension zip but it is not loaded in your environment. Change your environment to provide this extension.

Low PHP script execution time
Your max_execution_time is low. While TYPO3 often runs without problems with 30 seconds, it may still happen that script execution is stopped before finishing calculations. You should monitor the system for messages in this area and maybe raise the limit to 240 seconds:
