Cannot log into backend on new site

Hiya!

I did a search but I could not find this particular issue..

I migrated my site to another webhost (same domain) and I cannot login to the php admin backend page nor can I log into the bbpress forums on the site..it just …reloads the page and nothing happens.

I didn’t change any settings on Duplicator, I basically left everything as is.

Any thoughts as to what I need to check?
