Safari iOS 10.3.1 not clearing Safari cache

If you haven't tried it like this, give it a go; it just worked for me three times. Before clearing history within Safari open a new tab; close the "surfed with" tab; then clear Safari history from the "not surfed with" tab.

Clearing from a "surfed with" tab frequently/mostly leaves a Website Data entry for me, even if only for 0 KB from a domain(s).

I'm stumped.

I wouldn't worry about it, a lot stumps me.

I wouldn't worry much about the websites not deleting either, but that's just me.

There is a perfectly rational reason for the behavior, darn if we know what it is.

Have you tried making both iTunes and iCloud backups, erasing your iPad , then setting it up as new ? If not don't, too much work.

As much as I hate doing it I'm going to delete my website data. I'll be back.

Do you have those websites listed as "Favorites" anywhere ?

AAlready tried that. I was alarmed enough about discovering CloudFront on my iPhone that I did a complete reset, and restored it from an older backup. Had to run updates, etc. It didn't change a thing. Still have CloudFront the minute I use Safari and the cache has the half a dozen undeletable items, none of them zero sized. And, I DO notice several performance hits and problems, from Safari locking up entirely, to missing passwords. I am still getting the ten or so phishing emails from "FedEx", etc. No idea if these are related, but I havent experienced this level of problems with Apple ever. It needs mentioning, too, that I just was contacted by CITIBank that my Costco VISA card was used for a charge of just under $800 in California. I don't use that for anything but Costco and Amazon purchases, have limited it to that for years. How would hackers get my credit card number, expiration date? I cannot think of another manner. Something is very wrong and Apple needs to be looking into it.

I'm stumped.

You're welcome.

File this with the notation "he couldn't let go of the inconsistency" -- For cookies, I have selected "Allow from Current Website Only". I'm using the content blocker Fx Focus in Safari.

Experienced/experiencing similar Safari issues in both iOS and macOS, and turned to the ASC discussions for help. Tried a few suggestions for my MacBook Pro, including Empty Caches from Safari's Develop menu, but the web site "databases" persisted. Finally bit the bullet and followed a suggestion to send ALL the contents within ~/Library/Safari/Databases to the Trash Bin yesterday. That immediately cleared those database entries from the MBP, with seemingly no ill effect, after which I emptied the Trash. Within the ASC discussion "Why can't I delete website data in iOS 10.3?", member Drocmirage provided a somewhat convoluted multi-step procedure for deleting persistent website data. That procedure eliminated one of the two entries from my iPad Pro 9.7, but I couldn't get it to work for the other site (microsoftstore.com), so am hoping Apple comes through with a fix in their next iOS, and macOS, updates. Should mention that the persistent data on the Mac vs. iPad were from different web sites (none in common on both machines), even though I share browsing history via iCloud. Also, I had indeed browsed all of those sites within the last several weeks. Other than experiencing the same Safari cache quirkiness a great many of us have, there has been no evidence of mischief on any of our family's five Mac/iOS devices, nor any of our accounts thus far.

I did the same thing with my iPhone - a complete reset, "Erase all content and settings"; the Non-delectable items, CloudFront, all of it, was back within a day. My concern is that my credit card information was stolen and used. I have no idea if this was the cause of i, but since I don't use it for anything but Costco gas and groceries, and Amazon and iTunes store, I'm VERY suspicious And concerned. I filed this as a bug with Apple, and no one has contacted me about it, either.

Apple was working on a hack proof phone, along the lines of the Turing phone and Boeing Black. I want one. I'm sick of hackers.

It's a real pain and my iPhone has the same problem.

If it really bothers you then do what I did, restore the phone back to factory settings and start again. Fortunately I have mac book too so restoring wasn't too much of a problem. At least you'll have a clean machine until the next time you try to clear the cache and find another batch of immovables

Hello,

I'm having the same problem on my iPhone 6 plus (iOS 10.3.1). Safari web data will not delete. Tried the same processes mentioned in this thread but no success. I tried Reset - Reset All Settings, and Reset - Erase All Content and Settings and neither worked. Next was restoring the phone via iTunes and used backup data to restore it. That didn't work either. Costco.com, weather.com, congress.gov are a few that won't delete. Some data won't delete but will reduce to 0 bytes, while others will not delete and they continue to take up space. I've seen a few other threads talking about the same issue. I submitted a feedback form to Apple detailing the problem. Hope they fix it soon. Thanks.

You don't have to set up as new. But you can hit General settings > reset> reset all settings. And it will clear. Without erasing your data. However it will clear any fingerprints you have saved.
