Hey @ariban99,
Do you have a staging/test site for your live site? If you do, can you please deactivate all plugins there to confirm if the issue is indeed solely from SliceWP?
If you don’t, can you please enable the “System Status” feature from SliceWP > Settings > Tools (tab) and send over the system status? It lists all of your active plugins. I’d like to try and replicate your setup and see what can be conflicting.
Also, considering that this forum is public, if you believe that the system status contains information that you may not want to share publicly, please contact us privately via our website (here, https://slicewp.com/contact/).
As far as redirect goes, you can use the Redirection plugin (https://www.ads-software.com/plugins/redirection/) or a similar plugin.
Thank you and best wishes,
Mihai
