Thanks @bedas for a hint! Unfortunatly I do not have this option on my version, for some reason, but I downloaded new version 5.6.1 and reinstalled with downlaoding all files and folders form 5.6.1.zip except wp-conten folder, for now it works fine will see if there will be no issues on next update with new release.
Seriously? no one else have thsi issue only me and @bedas ?
