If anyone else is getting them then I think the casino is not yet fully tested or is still being worked. It is better to stay away from it as it might harm your computer. Before marketing the casino on the forum the team should have first tested and checked it for errors. It does not create a good impression when you start marketing a flawed platform for gambling.
Yes, I got that error It is a glitch and it is not good for the platform and unfair for players if they are going to play with a glitch and not properly configured, they should have tested their platform a hundred times, it should first go to beta and alpha testing and make sure that the platform's features are all working.
I don't want to discriminate but I will not yet play on casinos that show glitches and bugs there are risks attached to them, and there are many issues and questions but I guess we and OP are in different time zones, he is still resting while we are checking their platform.
Representatives and admins should create threads on the time where they can allocate time to answering questions and issues, he may have posted this before going to bed.
Looks like @OP is still checking out other stuff so hasn't come back to the thread yet. Hopefully, he can provide more information about the site. He can buy a Copper Membership as suggested by other members so he can display images from his site or promotions he has created.
If you look closely, the site is similar to Stake.com because I saw the template it uses. But that's not a problem because as long as he and the casino team can provide good service, the casino can develop well.
