Website disappeared after deactivating JetPack

Thanks, ayeshaumar for all your suggestions.

I did #1 immediately. No change. Site keeps going to /default

I can’t do #2 because I don’t know what my DNS settings were BEFORE doing this. Trying to find out what they are now, but not sure that alone will help me.

I can’t do #3 or #4, because my entire site disappeared from WordPress, so I have no dashboard from which to reactivate or inactivate. I tried getting it directly from Jetpack, but because the site was externally hosted they apparently will not deal with me.

I can’t access Jetpack support because I did not have the paid version, just the one that was offered by WordPress.

I did find another poster who says the same thing happened to her. So, it DOES appear that this can happen with JetPack.

Fortunately, I had backed up earlier on UpdraftVault. Waiting to hear from them whether this might salvage the situation.

Thanks again.

Very odd that the helpful suggestions offered by others seem to have disappeared! At any rate, the problem resolved itself at almost the exact same time I received notice that WP had updated to 6.2…. so I am wondering whether somehow the changeover caused all of this angst.

At any rate, my site is back up and running.
THANKS to this community for being so responsive!
