Yeah… the hosting provider changed the name servers a while ago and I missed their emails. Stupid me. Marked as solved.
@moderator can you please edit my domain name from the previous post as I’ve been getting spam emails for technical support companies all day long? Thanks a lot!
I installed those plugins and disabled all the plugins I had and changed the theme to a default one. I still get that error on other sites using other themes, so I guess it’s probably safe to assume it’s a hosting issue, right? Thank you!
ps: what is weird is that some other site running on the same server is working ok 🙂
Hey! One of the sites is [redacted] . Thank you for your help!
