Hi,
as you probably noticed, the forum was offline for the past ~18 hours. This outage was due to a problem on the hosting side, and it has affected other sites on the same server too. We are still waiting for a statement from our hosting provider explaining the reason for the outage, but at least the forum is back online. We apologize for any inconvenience this may have caused, and thanks for your patience.
EDIT: Unfortunately it seems I spoke too soon: some pages still show an error when they are opened, and they are successfully opened only after 3-4 attempts. According to a post by one of the hosting provider's admin, the problem seems to be caused by recent Google Warnings about malware on some of the sites hosted by them, and by the software they are deploying in order to improve the security.
I can assure you that OESF is malware free: we have registered it on the Google Search Console a year ago, and it currently reports that no malware can be found here. I often check the Security status there to verify that no malware has been installed in the meanwhile.
The situation is anyway getting better, and I hope that soon we won't have any more problems. As before, thanks for your patience.
