Hi Tazo,
I have installed your plugin today on 6 march 2018, unfortunately i also find the same problem.
On trying to open phpmyadmin, i got redirected to a blank page with this message:
“Go back (to the last page from where you tried to enter this page) and refresh that page, and then click “enter PhpMyAdmin” button again. If you still have problems, open ticket at Support pages, probably something breaks a normal page-load in dashboard.”
Tazo, Kindly look into the matter asap.
Thanks
