Hi runningpuff, thanks for your post.
If it is only happening with Firefox, this might be browser related, in that case we wouldn't be able to assist any further. However, if it happens with all browsers, please take a screenshot of the error in question upload it here, and we will take a further look for you no problem.
Thank you,
Marco
