Hello,
i would suggest you to follow the following and check if it works??
- Please deactivate all installed 3rd party plugins.
- Delete browsers cache especially cache plugin.
- if any extra codes added by you then remove it.
- Re-save permalinks.
deactivate everything other than wplms defaults then check if it works.
one of the plugins is interfering with the normal process.
i have checked on your website there are many plugins installed. one of them is conflicting with the normal process of wplms. please let the woo-commerce plugin activated and deactivate all other woo extensions.
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.
if above does not work in that case share admin URL and credentials in a private reply. please let me know your response.
