Missing tables?

[purwa]

Hello.

one of my client site was build with pw 2.3, everything run smoothly until 3 days ago its  throwing error (missing templates table). I Checked mysql and the sessions table also missing, any clue what is causing this?

Sounds like the table(s) got corrupted somehow. Are they completely gone? If not you could try to run a repair over the tables.

I'm not sure what could be the cause. Perhaps a corrupted sector on the hard drive?
