Description

EXT:linkvalidator/Classes/Linktype/ExternalLinktype.php, function checkLink near line 88:

                // HEAD was not allowed or threw an error, now trying GET
                $options['headers']['Range'] = 'bytes = 0 - 4048';
                $isValidUrl = $this->requestUrl($url, 'GET', $options);

According to RFC 7233 there can be no spaces in range specification. Some web servers strictly follow this and throw a 416 http error.

Simple remove spaces like this:

                // HEAD was not allowed or threw an error, now trying GET
                $options['headers']['Range'] = 'bytes=0-4048';
                $isValidUrl = $this->requestUrl($url, 'GET', $options);

[BUGFIX] Incorrect HTTP range specification in Linkvalidator

Range specifications in HTTP may not include spaces. While many
web servers tolerate them, some return a 416 HTTP error. This
change makes range request from Linkvalidator to follow RFC 7233.
