Session issue

I installed the Shapely Theme and a plug-in for the hotel rooms reservation. The plug-in does not work well because the plug-in developer after a specific verification on their code tells me this: "In your wp-site session is not working that’s for this issue coming.Please solve session That issue after this issue will be automatically solve.Please contact theme developer "
Please let me know I can solve it . Many thanks in advance.


Session handling is not done via Theme, it is done by WordPress, I don’t know what issues he is telling. You can try changing the theme to a default theme like twentysixteen and see that the issue was gone? In that case, it is a theme issue, if that is not even working on the default theme means something wrong in your configuration. Please ask the detailed error with the plugin author and search for the solution, or post it here, we can happy to help you to find what cause that.

Let us know,
