Tried 3-4 different versions 4.X (even 4.6) with the same result. Due to urgency of the matter I have purchased a hosting account and setup 4.7.5 without a glitch.
It seem’s to be a sharing issue, maybe for some reason cookies between the two sites are getting mixed up?
I can try later on (in about 2 weeks) to test 4.8 (It’s still beta?).
I also want to try the Multi hosting (Network) setup, maybe this will address the issue.
downgrade to 4.7.4, just to test, same issue.
Could this be connected to the same server hosting another wp?
My issue continues, refresh or re-login doesn’t bypass the issue. I have cleared the cache of the browser multiple times (even though it’s new, no caching should have happened anyhow), but to no avail.
