[TYPO3-english] linkvalidator: faulty link not recognised

[Dennis Hoffland]

Hello,

I have activated the linkvalidator extension in the Extension Manager. Then I created a broken test link as shown in this video: https://jweiland.net/typo3-hosting/service/video-anleitungen/typo3-extensions/linkvalidator.html.

When I go Web > Info and select Linkvalidator and perfom the Check Links option, the linkvalidator reports "No broken links to show!". Obviously it doesn't recognise the broken link as faulty.

I use Typo3 6.2.10.

Any thoughts on what's going wrong?

Kind regards,

Dennis

PS. In the System environment check in the Install Tool I get:

Some PHP functions disabled
disable_functions=escapeshellarg escapeshellcmd exec passthru proc_close proc_get_status proc_nice proc_open proc_terminate shell_exec system popen pclose
These function(s) are disabled. TYPO3 uses some of those, so there might be trouble. 

Not sure if this is somehow related to the issue described above.
