Safari website data on your iPhone or iPad - How to clear

OS

Safari/Preferences/Advanced - enable the Develop menu, then go there and Empty Caches. Quit/reopen Safari and test. Then try Safari/History/Show History and delete all history items. Quit/reopen Safari and test. You can also try try Safari/Clear History…. The down side is it clears all cookies. Doing this may cause some sites to no longer recognize your computer as one that has visited the web site. Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J. When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder. Select Library/Caches/com.apple.Safari/Cache.db and move it to the trash.

Go to Safari Preferences/Extensions and turn all extensions off. Test. If okay, turn the extensions on one by one until you figure out what extension is causing the problem.

Have tried on iPad but no change. It seems ok on iPhone. Have tried everything on Mac OS but no change. I have not run that program yet but will do. Safari on iOS and OS is fine on everything other than Facebook. This is just a Facebook issue it seems

Clean up: ⓘ

/Library/LaunchDaemons/com.nalpeiron.netpro.plist

Executable not found!

One orphan file found. [Clean up]

Click Clean up.

I don't see any installed software that could be contributing to the problem.

Try another browser as a test.

Firefox 10.9 or higher

Opera Browser 10.9 or higher

SeaMonkey 10.9 or higher

Waterfox 10.8 or higher

Looks like it might be a Facebook issue as it is the same on Chrome but it works ok on the Facebook App. Where using Safari I went into preferences for the News Feed and changed them to read Most Recent rather than Top Stories. On that setting Safari is working fine (at the moment) on Mac and IOS.

From your Safari menu bar (top of your screen) click Safari > Preferences then select the Security tab.

Deselect: Enable plug ins

Quit and relaunch Safari. If that helped, then follow the instructions for troubleshooting plugins here.

And also try deleting the cache and cookies.

Back to the menu bar, click Safari > Reset Safari

Select: Clear History (also empies the cache)

Now go to Safari > Preferences again then select the Privacy tab.

Click: Remove All Website Data (deletes cookies)

Quit and relaunch Safari to test.

I am having exactly the same problem and am seeing it my iPad and my mac mini. IT does not happen when browsing the groups I belong to but happens consistently when browsing news feed.
