Create Record Here and Permalink plugin error on CMSB 3.09

Hi again,

I am trying to setup my plugins as usual for my new installation of v.3.09 but I am having troubles activating the  Create Record Here and Permalink plugin.

When I activate the Create Record Here plugin it gives me an error page when pressing the Save button. The Apply button and Save and Copy button does not give me this error.

MySQL Error: Access denied for user 'studiohart'@'localhost' (using password: NO)

The error log:

E_WARNING: mysql_query(): A link to the server could not be established
/xxx/cmsb/plugins/createRecordHere_1_01/createRecordHere.php (line 46)
https://xxx/cmsb/admin.php?menu=blog&saved=7

The same error page appears when I activate the Permalink plugin (v.1.05 & 1.07).

They work fine on 3.07 and I've checked my database information on data.settings.php. I haven't tried 3.08.

Please tell me how I can solve this problem. 

Thank you!

Hiroko
