When I click save options on currency switcher(WPCS) plugin after the changes, it will redirect to server error 403 forbidden. why it's happening kindly explain it.
A 403 Forbidden error means that you do not have permission to view the requested file or resource. While sometimes this is intentional, other times it is due to misconfigured permissions. The top reasons for this error are permissions or .htaccess error.
So, to fix it you have to do the following:
go to your wordpress site dashboard then settings=>permalinks and save the settings (save chnages)
If not fix from the above option then you have to contact your hosting support with details you are facing.
Otherwise I would like to recommend please contact Item Author to get item support How to Contact your purchased Item Author and let them know. Item author will be happy to assist you.
Thank you for your reply. I have tried with the permalinks, but still I am getting this error. Okay I will check your reaming points.
