Have I sent a PM or not?

Recently I've replied to a couple of PM's but have no way to tell if they were actually sent and received. In the General Settings I've ticked the "save a copy of the message in my Sent folder" box but when I try to save the change I get this error message:

Fatal error: xcache_count(): xcache.admin.user and/or xcache.admin.pass settings is not configured. Make sure you've modified the correct php ini file for your php used in webserver. in /home/woodwork/public_html/dbtech/dbseo/includes/class_datastore.php on line 422

Does this indicate I've stuffed up somewhere? And if this is an error outside of my control is there any way to see if the PM's I think I have sent actually did go?

No Idea why you got that message.

I've changed your settings to "Save a copy of sent messages in my Sent Items" so it should be ok now.

Try it and let us know please.

Yep; all good now.

Many thanks; :2tsup:
