   It looks like a plugin is probably causing the issue.

   Disable all your plugins. Hopefully you won't get the error then.

   Then re-enable the plugins one-by-one until the issue reappears. This will indicate which plugin isn't behaving.

   If you can't log in, disable the plugins by one of the methods on this page

   I have the same problem. Deactivating and deleting plugins doesn't work.

   Also tried the other recommended things that are used to resolve the header warning thing, but nothing seems to work.

   Is a reinstall going to be the only solution?
