[Closed] Events Manager plugin

I have issues with tickets names not saving in Welsh on dtawales.org .uk but they seem to work on an older staging site i have - hidden link. Tickets save initially when creating an event but if you edit them they revert to English.

If i provide Admin access, could someone take a look please as to why it works on the staging site on not on live. I have also reached out to the plugin author of Events Manager Pro and am waiting to hear.

Thanks
Jon
