please follow these steps
- Please deactivate all installed 3rd party plugins(leave wplms plugins activated).
- Delete browsers cache especially cache plugin, if any installed.
- Re-save permalinks
have checked on your website there is so many plugins installed. one of them is conflicting with login.
Please go to the plugin page and try to deactivate all 3rd party plugins. and check if it resolves the issue. then activate plugins 1 by 1 and check which plugin is causing this issue.
once you are done with identifying that wicked plugin. i suggest you to not activate that plugin.
