Last time this happened it took 2 weeks of posting to correct but I am seeing a pattern and need help-

At this time in my developing of my cart I have had little reason to go into my phpmyadmin. but yesterday I was trying to do the add properties procedure and it logged into phpmyadmin.
Everything was great.

This morning I am locked out.

The last time (about a month ago) I logged into phpmyadmin - the exact same thing happened. I am totally locked out of my site. and my admin. I get an error.

0 DB_ERROR_NOT_CONNECTED
in:
[select * from project_version WHERE project_version_key = 'Zen-Cart Database' ]
If you were entering information, press the BACK button in your browser and re-check the information you had entered to be sure you left no blank fields.

Any ideas - I have not gone live as of yet I am busy working on security.

TIA
