Can't remove website data
On my Macbook Pro, using Maverick, 10.9.5, I am unable to remove my website data under Privacy settings in Safari.
It looks at first that it removes the data, but then all 532 datas show back up. I emptied the cache, History, then Website data again (4 times in all) but same thing, it all comes back within a few seconds. I have to log into my websites again even with the 532 datas still there. I'm dumfounded. I also have tried quitting Safari and opening it back up. Here is a screenshot taken right after all the data was removed and it looked empty until this popped back up.
PS My info on the Macbook looks like I'm using Yosemite but I'm not, I'm back to my old partition using Maverick.
Any help would be appreciated. Thanks, Martha
