Flush TYPO3 and PHP Cache

This action directly clears all registered caches including opcode cache. This utility is also present in TYPO3’s backend: Top Bar > Clear Cache > Flush all caches. A fatal error will be thrown if a broken extension is detected. If this occurs, use the extension tester utility (Upgrade > Check For Broken Extensions).
