Hi @dominokozmali,
Thanks for leaving a review. I’m really sorry for the surprise charge for Broken Link Checker
Broken Link Checker is a free plugin, but if it scans more than 250 links in a month, then you’re automatically upgraded to the appropriate monthly plan to avoid interruption, so that BLC can continue scanning all the links on your site.
If BLC hasn’t scanned your site, or you don’t have more than 250 links on your site, then I recommend that you reach out to our Support team via the Contact form on our site. Please use the Basic Question form to reach us, and we’ll be happy to investigate and correct this.
