Cannot delete messages inside PM inbox and sent items

Seems there is a problem.. It is not allowing me to delete my old messages..

 

Just to round your report, Digitalpoint is having numerous glitches lately.

PMs cannot be deleted, PMs do not popup on notification, loging in welcomes you but instead of proceed takes you back to the sign in form, deleting your Blog's RSS feed temporary it's fine inside your control panel but it remains displayed throughout your posts.

It smells like an upcoming forum crash so please DP admin and/or moderators, make sure to backup the information more regularly than usual and work on an alternate location (not publicly open) to reinstall the software from the scratch and begin to transfer DP's database.

A titanic job but I know this by experience seeing crash one of the biggest hosting forums (in which I was staff) after beginning experiencing issues like this.
