Reinstalled after downloading version 2.3.5
Created a test file and added the simple link:
https://wishuponacure.org/temp.php
<a href="Templates/tel:+1-240-426-5766" class="link">(240) 426-5766</a> <i class="fas fa-phone brown"></i>
The exact same link is in the template but it does not work as it adds /Templates/ to the path...
Framework version 2.01 and lines referencing "tel:" are
preg_match($matchpat,$subStr,$subPats);
$ignore = '/^(https?%3A%2F%2F|https?:\/\/|mailto:|javascript:|cid:|callto:|wtai:|sms:|market:|geopoint:|ymsgr:|msnim:|gtalk:|skype:|sip:|whatsapp:|geo:|data:|tel:|#|\/)/i';
$combineDir = rel2abs($startDir,$endDir);
