Log in issue to StackExchnage [migrated]

I have posted the following question a month ago and now I am trying to edit or comment on it, but it does not allow me to do so. It says I don’t have 50 reputations, while in actual I have more than 50. Could someone figure it out, please?
"SciJewel" is my display name. Thanks!
