Hi Ipstenu,
Thanks for your information. I used a similar site before with techniques to edit my .htaccess file to obtain hotlink protection. But unfortunately with no solution.
I’m afraid that there is something wrong/interfering with the codes in my current .htaccess file. Sorry I wasn’t aware enough about the forum rules. I now used pastebin to show you the code:
<script src="https://pastebin.com/embed_js.php?i=RCNGtEmy"></script>
Thanks for your help.
