Hello,
I copied my site to a development environment and installed the core plugin. After I activate it, it redirects me to the homepage. If I try to go to the Dashboard or any admin page, it simply just refreshes the homepage. I tried deactivating every other plugin and it still happens. I don’t think it is my theme because a few weeks ago I duplicated the site and installed it and this did not happen, however, I needed to re-create the site and start fresh because of other problems and new some changes on the production site (new content, plugin updates, CSS changes, other minor things, maybe a WordPress update). I can send you the wordpress login in a private reply. However Geodirectory is disabled. If you login and activate it, you won’t be able to get back into the Plugins or any admin page. Thank you.
